+title: Brand guidelines
+---
+
+Have a need for Bootstrap's brand resources? Great! We have only a few guidelines we follow, and in turn ask you to follow as well. These guidelines were inspired by MailChimp's [Brand Assets](http://mailchimp.com/about/brand-assets/).
+
+## Mark and logo
+
+Use either the Bootstrap mark (a capital **B**) or the standard logo (just **Bootstrap**). It should always appear in Helvetica Neue Bold. **Do not use the Twitter bird** in association with Bootstrap.
+
+<div class="bs-brand-logos">
+ <div class="bs-brand-item">
+ <div class="bs-docs-booticon bs-docs-booticon-lg">B</div>
+ </div>
+ <div class="bs-brand-item inverse">
+ <div class="bs-docs-booticon bs-docs-booticon-lg bs-docs-booticon-inverse">B</div>
+ </div>
+</div>
+<div class="bs-brand-logos">
+ <div class="bs-brand-item">
+ <h1>Bootstrap</h1>
+ </div>
+ <div class="bs-brand-item inverse">
+ <h1>Bootstrap</h1>
+ </div>
+</div>
+
+## Download mark
+
+Download the Bootstrap mark in one of three styles, each available as an SVG file. Right click, Save as.
+
+<div class="bs-brand-logos">
+ <div class="bs-brand-item">
+ <img class="svg" src="{{ site.baseurl }}assets/brand/bootstrap-solid.svg" alt="Bootstrap">
+ </div>
+ <div class="bs-brand-item inverse">
+ <img class="svg" src="{{ site.baseurl }}assets/brand/bootstrap-outline.svg" alt="Bootstrap">
+ </div>
+ <div class="bs-brand-item inverse">
+ <img class="svg" src="{{ site.baseurl }}assets/brand/bootstrap-punchout.svg" alt="Bootstrap">
+ </div>
+</div>
+
+## Name
+
+The project and framework should always be referred to as **Bootstrap**. No Twitter before it, no capital _s_, and no abbreviations except for one, a capital **B**.
+
+<div class="bs-brand-logos">
+ <div class="bs-brand-item">
+ <h3>Bootstrap</h3>
- <span class="glyphicon glyphicon-remove"></span>
++ <strong class="text-success">Right</strong>
+ </div>
+ <div class="bs-brand-item">
+ <h3 class="text-muted">BootStrap</h3>
- <span class="glyphicon glyphicon-remove"></span>
++ <strong class="text-warning">Wrong</strong>
+ </div>
+ <div class="bs-brand-item">
+ <h3 class="text-muted">Twitter Bootstrap</h3>
++ <strong class="text-warning">Wrong</strong>
+ </div>
+</div>
+
+## Colors
+
+Our docs and branding use a handful of primary colors to differentiate what *is* Bootstrap from what *is in* Bootstrap. In other words, if it's purple, it's representative of Bootstrap.

+
+<div class="bs-callout bs-callout-warning">
+ <h4>Tooltips & popovers in button groups require special setting</h4>
+ <p>When using tooltips or popovers on elements within a <code>.btn-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>
+</div>
+
++<div class="bs-callout bs-callout-warning">
++ <h4>Ensure correct <code>role</code> and provide a label</h4>
++ <p>In order for assistive technologies – such as screen readers – to convey that a series of buttons is grouped, an appropriate <code>role</code> attribute needs to be provided. For button groups, this would be <code>role="group"</code>, while toolbars should have a <code>role="toolbar"</code>.</p>
++ <p>One exception are groups which only contain a single control (for instance the <a href="#btn-groups-justified">justified button groups</a> with <code><button></code> elements) or a dropdown.</p>
++ <p>In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct <code>role</code> attribute. In the examples provided here, we use <code>aria-label</code>, but alternatives such as <code>aria-labelledby</code> can also be used.</p>

+
+Make a group of buttons stretch at equal sizes to span the entire width of its parent. Also works with button dropdowns within the button group.
+
+<div class="bs-callout bs-callout-warning">
+ <h4>Handling borders</h4>
+ <p>Due to the specific HTML and CSS used to justify buttons (namely <code>display: table-cell</code>), the borders between them are doubled. In regular button groups, <code>margin-left: -1px</code> is used to stack the borders instead of removing them. However, <code>margin</code> doesn't work with <code>display: table-cell</code>. As a result, depending on your customizations to Bootstrap, you may wish to remove or re-color the borders.</p>

+title: Forms
+---
+
+Bootstrap normalizes common HTML5 form elements and adds a number of layout options for building forms of all sizes.
+
+## Example form
+
+Individual form controls automatically receive some global styling. All textual `<input>`, `<textarea>`, and `<select>` elements with `.form-control` are set to `width: 100%;` by default. Wrap labels and controls in `.form-group` for optimum spacing.
+
+{% example html %}
- <form class="form-inline" role="form">
++<form>
+ <div class="form-group">
+ <label for="exampleInputEmail1">Email address</label>
+ <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
+ </div>
+ <div class="form-group">
+ <label for="exampleInputPassword1">Password</label>
+ <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
+ </div>
+ <div class="form-group">
+ <label for="exampleInputFile">File input</label>
+ <input type="file" id="exampleInputFile">
+ <p class="help-block">Example block-level help text here.</p>
+ </div>
+ <div class="checkbox">
+ <label>
+ <input type="checkbox"> Check me out
+ </label>
+ </div>
+ <button type="submit" class="btn btn-secondary">Submit</button>
+</form>
+{% endexample %}
+
+<div class="bs-callout bs-callout-warning">
+ <h4>Don't mix form groups with input groups</h4>
+ <p>Do not mix form groups directly with <a href="/components/#input-groups">input groups</a>. Instead, nest the input group inside of the form group.</p>
+</div>
+
+## Inline forms
+
+Add `.form-inline` to your `<form>` for left-aligned and inline-block controls. **This only applies to forms within viewports that are at least 768px wide.**
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Requires custom widths</h4>
+ <p>Inputs and selects have `width: 100%;` applied by default in Bootstrap. Within inline forms, we reset that to `width: auto;` so multiple controls can reside on the same line. Depending on your layout, additional custom widths may be required.</p>
+</div>
+<div class="bs-callout bs-callout-warning">
+ <h4>Always add labels</h4>
+ <p>Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the `.sr-only` class.</p>
+</div>
+
+{% example html %}
- <div class="form-group">
- <div class="input-group">
- <div class="input-group-addon">@</div>
- <input class="form-control" type="email" placeholder="Enter email">

++ <div class="input-group-addon">.00</div>
++ </div>
++ </div>
++ <button type="submit" class="btn btn-primary">Transfer cash</button>
+</form>
+{% endexample %}
+
+## Horizontal forms
+
+Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding `.form-horizontal` to the form. Doing so changes `.form-group`s to behave as grid rows, so no need for `.row`.
+
+{% example html %}
- <form class="form-horizontal" role="form">
++<form class="form-horizontal">
+ <div class="form-group">
+ <label for="inputEmail3" class="col-sm-2 control-label">Email</label>
+ <div class="col-sm-10">

+ </div>
+ </div>
+ <div class="form-group">
+ <label for="inputPassword3" class="col-sm-2 control-label">Password</label>
+ <div class="col-sm-10">
+ <input type="password" class="form-control" id="inputPassword3" placeholder="Password">
+ </div>
+ </div>
+ <div class="form-group">
+ <div class="col-sm-offset-2 col-sm-10">
+ <div class="checkbox">
+ <label>
+ <input type="checkbox"> Remember me
+ </label>

+
+## Supported controls
+
+Examples of standard form controls supported in an example form layout.
+
+### Inputs
+
+Most common form control, text-based input fields. Includes support for all HTML5 types: `text`, `password`, `datetime`, `datetime-local`, `date`, `month`, `time`, `week`, `number`, `email`, `url`, `search`, `tel`, and `color`.
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Type declaration required</h4>
+ <p>Inputs will only be fully styled if their `type` is properly declared.</p>
+</div>
+
+{% example html %}
+<input type="text" class="form-control" placeholder="Text input">
+{% endexample %}
+
+<div class="bs-callout bs-callout-info">
+ <h4>Input groups</h4>
+ <p>To add integrated text or buttons before and/or after any text-based `<input>`, <a href="../components/#input-groups">check out the input group component</a>.</p>
+</div>
+
+### Textarea
+
+Form control which supports multiple lines of text. Change `rows` attribute as necessary.
+
+{% example html %}
+<textarea class="form-control" rows="3"></textarea>
+{% endexample %}
+
+### Checkboxes and radios
+
+Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
+
+A checkbox or radio with the `disabled` attribute will be styled appropriately. To have the `<label>` for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the `.disabled` class to your `.radio`, `.radio-inline`, `.checkbox`, `.checkbox-inline`, or `<fieldset>`.
+
+#### Default (stacked)
+
+{% example html %}
+<div class="checkbox">
+ <label>
+ <input type="checkbox" value="">
+ Option one is this and that—be sure to include why it's great
+ </label>
+</div>
+<div class="checkbox disabled">
+ <label>
+ <input type="checkbox" value="" disabled>
+ Option two is disabled
+ </label>
+</div>
+
+<div class="radio">
+ <label>
+ <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
+ Option one is this and that—be sure to include why it's great
+ </label>
+</div>
+<div class="radio">
+ <label>
+ <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
+ Option two can be something else and selecting it will deselect option one
+ </label>
+</div>
+<div class="radio disabled">
+ <label>
+ <input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
+ Option three is disabled
+ </label>
+</div>
+{% endexample %}
+
+#### Inline
+
+Use the `.checkbox-inline` or `.radio-inline` classes on a series of checkboxes or radios for controls that appear on the same line.
+
+{% example html %}
+<label class="checkbox-inline">
+ <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
+</label>
+<label class="checkbox-inline">
+ <input type="checkbox" id="inlineCheckbox2" value="option2"> 2
+</label>
+<label class="checkbox-inline">
+ <input type="checkbox" id="inlineCheckbox3" value="option3"> 3
+</label>
+
+<label class="radio-inline">
+ <input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
+</label>
+<label class="radio-inline">
+ <input type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2"> 2
+</label>
+<label class="radio-inline">
+ <input type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3"> 3
+</label>
+{% endexample %}
+
+#### Without labels
+
+Should you have no text within the `<label>`, the input is positioned as you'd expect. **Currently only works on non-inline checkboxes and radios.**
+
+{% example html %}
+<div class="checkbox">
+ <label>
+ <input type="checkbox" id="blankCheckbox" value="option1">
+ </label>
+</div>
+<div class="radio">
+ <label>
+ <input type="radio" name="blankRadio" id="blankRadio1" value="option1">
+ </label>
+</div>
+{% endexample %}
+
+### Selects
+
+Use the default option, or add `multiple` to show multiple options at once.
+
+{% example html %}
+<select class="form-control">
+ <option>1</option>
+ <option>2</option>
+ <option>3</option>
+ <option>4</option>
+ <option>5</option>
+</select>
+
+<select multiple class="form-control">
+ <option>1</option>
+ <option>2</option>
+ <option>3</option>
+ <option>4</option>
+ <option>5</option>
+</select>
+{% endexample %}
+
+## Static controls
+
+When you need to place plain text next to a form label within a form, use the `.form-control-static` class on a `<p>`.
+
+{% example html %}
- <form class="form-inline" role="form">
++<form class="form-horizontal">
+ <div class="form-group">
+ <label class="col-sm-2 control-label">Email</label>

++ <p>By default, browsers will treat all native form controls (<code><input></code>, <code><select></code> and <code><button></code> elements) inside a <code><fieldset disabled></code> as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes <code><a ... class="btn btn-*"></code> elements, these will only be given a style of <code>pointer-events: none</code>. As noted in the section about <a href="#buttons-disabled">disabled state for buttons</a> (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11, and won't prevent keyboard users from being able to focus or activate these links.

+## Validation

+Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add `.has-warning`, `.has-error`, or `.has-success` to the parent element. Any `.control-label`, `.form-control`, and `.help-block` within that element will receive the validation styles.
+
+{% example html %}
+<div class="form-group has-success">

+You can also add optional feedback icons with the addition of `.has-feedback` and the right icon.
+
+<div class="bs-callout bs-callout-warning">
+ <h4>Icons, labels, and input groups</h4>
+ <p>Manual positioning of feedback icons is required for inputs without a label and for <a href="../components#input-groups">input groups</a> with an add-on on the right. You are strongly encouraged to provide labels for all inputs for accessibility reasons. If you wish to prevent labels from being displayed, hide them with the `sr-only` class. If you must do without labels, adjust the `top` value of the feedback icon. For input groups, adjust the `right` value to an appropriate pixel value depending on the width of your addon.</p>

+## Control sizing
+
+Set heights using classes like `.input-lg`, and set widths using grid column classes like `.col-lg-*`.
+
+{% example html %}

+<input class="form-control" type="text" placeholder="Default input">
+<input class="form-control input-sm" type="text" placeholder=".input-sm">
+
+<select class="form-control input-lg"></select>
+<select class="form-control"></select>
+<select class="form-control input-sm"></select>
+{% endexample %}
+
+Quickly size labels and form controls within `.form-horizontal` by adding `.form-group-lg` or `.form-group-sm` to existing `.form-group`s.
+
+{% example html %}
++<form class="form-horizontal">
+ <div class="form-group form-group-lg">
+ <label class="col-sm-2 control-label" for="formGroupInputLarge">Large label</label>
+ <div class="col-sm-10">

+ </div>
+ </div>
+</form>
+{% endexample %}
+
+## Column sizing
+
+Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.
+
+{% example html %}
+<div class="row">
+ <div class="col-xs-2">
+ <input type="text" class="form-control" placeholder=".col-xs-2">

+
+### Contextual colors
+
+Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.
+
+{% example html %}
+<p class="text-muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
+<p class="text-primary">Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
+<p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
+<p class="text-info">Maecenas sed diam eget risus varius blandit sit amet non magna.</p>
+<p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
+<p class="text-danger">Donec ullamcorper nulla non metus auctor fringilla.</p>
+{% endexample %}
+
+<div class="bs-callout bs-callout-info">
+ <h4>Dealing with specificity</h4>
+ <p>Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <code><span></code> with the class.</p>
+</div>
++<div class="bs-callout bs-callout-warning">
++ <h4>Conveying meaning to assistive technologies</h4>
++ <p>Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (the contextual colors are only used to reinforce meaning that is already present in the text/markup), or is included through alternative means, such as additional text hidden with the <code>.sr-only</code> class.</p>
++</div>
+
+### Contextual backgrounds
+
+Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.
+
+{% example html %}
+<div class="bg-primary">Nullam id dolor id nibh ultricies vehicula ut id elit.</div>
+<div class="bg-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</div>
+<div class="bg-info">Maecenas sed diam eget risus varius blandit sit amet non magna.</div>
+<div class="bg-warning">Etiam porta sem malesuada magna mollis euismod.</div>
+<div class="bg-danger">Donec ullamcorper nulla non metus auctor fringilla.</div>
+{% endexample %}
+
+<div class="bs-callout bs-callout-info">
+ <h4>Dealing with specificity</h4>
+ <p>Sometimes contextual background classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a <code><div></code> with the class.</p>
+</div>
+
++<div class="bs-callout bs-callout-warning">
++ <h4>Conveying meaning to assistive technologies</h4>
++ <p>As with <a href="#helper-classes-colors">contextual colors</a>, ensure that any meaning conveyed through color is also conveyed in a format that is not purely presentational.</p>
++</div>
++
+### Close icon
+
+Use a generic close icon for dismissing content like modals and alerts. **Be sure to include screen reader text when you can** as we've done with `.sr-only`.
+
+{% example html %}
+<button type="button" class="close">
+ <span aria-hidden="true">×</span>
+ <span class="sr-only">Close</span>
+</button>
+{% endexample %}
+
+### Quick floats
+
+Float an element to the left or right with a class. `!important` is included to avoid specificity issues. Classes can also be used as mixins.
+
+{% example html %}
+<div class="pull-left">...</div>
+<div class="pull-right">...</div>
+{% endexample %}
+
+{% highlight scss %}
+// Classes
+.pull-left {
+ float: left !important;
+}
+.pull-right {
+ float: right !important;
+}
+
+// Usage as mixins
+.element {
+ .pull-left();
+}
+.another-element {
+ .pull-right();
+}
+{% endhighlight %}
+
+<div class="bs-callout bs-callout-warning">
+ <h4>Not for use in navbars</h4>
+ <p>To align components in navbars with utility classes, use <code>.navbar-left</code> or <code>.navbar-right</code> instead. <a href="../components/#navbar-component-alignment">See the navbar docs</a> for details.</p>
+</div>
+
+### Center content blocks
+
+Set an element to `display: block;` and center via `margin`. Available as a mixin and class.
+
+{% example html %}
+<div class="center-block">...</div>
+{% endexample %}
+
+{% highlight scss %}
+// Classes
+.center-block {
+ display: block;
+ margin-left: auto;
+ margin-right: auto;
+}
+
+// Usage as mixins
+.element {
+ .center-block();
+}
+{% endhighlight %}
+
+Easily clear `float`s by adding `.clearfix` **to the parent element**. Utilizes [the micro clearfix](http://nicolasgallagher.com/micro-clearfix-hack/) as popularized by Nicolas Gallagher. Can also be used as a mixin.
+
+{% highlight html %}
+<div class="clearfix">...</div>
+{% endhighlight %}
+
+{% highlight scss %}
+// Mixin itself
+.clearfix() {
+ &:before,
+ &:after {
+ content: " ";
+ display: table;
+ }
+ &:after {
+ clear: both;
+ }
+}
+
+// Usage as a Mixin
+.element {
+ .clearfix();
+}
+{% endhighlight %}
+
+### Showing and hiding content
+
+Force an element to be shown or hidden (**including for screen readers**) with the use of `.show` and `.hidden` classes. These classes use `!important` to avoid specificity conflicts, just like the [quick floats](#helper-floats). They are only available for block level toggling. They can also be used as mixins.
+
+Furthermore, `.invisible` can be used to toggle only the visibility of an element, meaning its `display` is not modified and the element can still affect the flow of the document.
+
+{% highlight html %}
+<div class="show">...</div>
+<div class="hidden">...</div>
+{% endhighlight %}
+
+{% highlight scss %}
+// Classes
+.show {
+ display: block !important;
+}
+.hidden {
+ display: none !important;
+ visibility: hidden !important;
+}
+.invisible {
+ visibility: hidden;
+}
+
+// Usage as mixins
+.element {
+ .show();
+}
+.another-element {
+ .hidden();
+}
+{% endhighlight %}
+
+### Screen readers and keyboard navigation
+
+Hide an element to all devices **except screen readers** with `.sr-only`. Combine `.sr-only` with `.sr-only-focusable` to show the element again when it's focused (e.g. by a keyboard-only user). Necessary for following [accessibility best practices](../getting-started/#accessibility). Can also be used as mixins.
+
+{% highlight html %}
+<a class="sr-only sr-only-focusable" href="#content">Skip to main content</a>
+{% endhighlight %}
+
+{% highlight scss %}
+// Usage as a Mixin
+.skip-navigation {
+ .sr-only();
+ .sr-only-focusable();
+}
+{% endhighlight %}
+
+### Image replacement
+
+Utilize the `.text-hide` class or mixin to help replace an element's text content with a background image.
+
+{% example html %}
+<h1 class="text-hide">Custom heading</h1>
+{% endexample %}
+
+{% highlight scss %}
+// Usage as a Mixin
+.heading {
+ .text-hide();
+}
+{% endhighlight %}

+layout: page
+title: Input group
+---
+
+Extend form controls by adding text or buttons before, after, or on both sides of any text-based `<input>`. Use `.input-group` with an `.input-group-addon` to prepend or append elements to a single `.form-control`.
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Textual <code><input></code>s only</h4>
+ <p>Avoid using <code><textarea></code> elements here as their <code>rows</code> attribute will not be respected in some cases.</p>
+</div>
+<div class="bs-callout bs-callout-warning">
+ <h4>Tooltips & popovers in input groups require special setting</h4>
+ <p>When using tooltips or popovers on elements within an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).</p>
+</div>
+<div class="bs-callout bs-callout-warning">
+ <h4>Don't mix with other components</h4>
+ <p>Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.</p>

+## Basic example
+
+Place one add-on or button on either side of an input. You may also place one on both sides of an input.
+
+**We do not support multiple add-ons on a single side.**
+
+**We do not support multiple form-controls in a single input group.**

+</div>
+{% endexample %}
+
+## Sizing
+
+Add the relative form sizing classes to the `.input-group` itself and contents within will automatically resize—no need for repeating the form control size classes on each element.
+
+{% example html %}
+<div class="input-group input-group-lg">
+ <span class="input-group-addon">@</span>

+
+## Button addons
+
+Buttons in input groups are a bit different and require one extra level of nesting. Instead of `.input-group-addon`, you'll need to use `.input-group-btn` to wrap the buttons. This is required due to default browser styles that cannot be overridden.

+title: Navbar

+
+The navbar is a simple wrapper for positioning branding, navigation, and other elements. It's easily extensible and with the help of our collapse plugin it can easily integrate offscreen content.
+
+### Basics
+
+Here's what you need to know before getting started with the navbar:
+
+- Navbars require a wrapping `.navbar` and either a color scheme class or custom styles.
+- When using multiple components in a navbar, some [alignment classes](#alignment) are required.
+- Navbars and their contents are fluid by default. Use [optional containers](#containers) to limit their horizontal width.
++- Ensure accessibility by using a `<nav>` element or, if using a more generic element such as a `<div>`, add a `role="navigation"` to every navbar to explicitly identify it as a landmark region for users of assistive technologies.
+
+### Branding
+
+Name your company, product, or project with `.navbar-brand`.
+
+{% example html %}
- </div>
++<nav class="navbar navbar-default">
+ <h3 class="navbar-brand">
+ <a href="#">Navbar</a>
+ </h3>
- <div class="navbar navbar-default">
++</nav>
+{% endexample %}
+
+### Navigation
+
+Use `.nav-pills` within a navbar for basic navigation.
+
+{% example html %}
- <a class="nav-link" href="#">Home</a>
++<nav class="navbar navbar-default">
+ <ul class="nav nav-pills">
+ <li class="nav-item active">
- </div>
++ <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Features</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Pricing</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">About</a>
+ </li>
+ </ul>
- <div class="navbar navbar-default">
++</nav>
+{% endexample %}
+
+### Inline forms
+
+Add an `.inline-form` within the navbar with nearly any combination of form controls and buttons.
+
+{% example html %}
- </div>
++<nav class="navbar navbar-default">
+ <form class="form-inline">
+ <input class="form-control" type="text" placeholder="Search">
+ <button class="btn btn-primary" type="submit">Search</button>
+ </form>
- <div class="navbar navbar-default">
++</nav>
+{% endexample %}
+
+### Containers
+
+Although it's not required, you can wrap a navbar in a `.container` or add one within for basic horizontal control.
+
+{% example html %}
- </div>
++<nav class="navbar navbar-default">
+ <div class="container">
+ <h3 class="navbar-brand">
+ <a href="#">Navbar</a>
+ </h3>
+ </div>
- <div class="navbar navbar-default">
++</nav>
+{% endexample %}
+
+{% example html %}
+<div class="container">
- </div>
++ <nav class="navbar navbar-default">
+ <h3 class="navbar-brand">
+ <a href="#">Navbar</a>
+ </h3>
- <div class="navbar navbar-default">
++ </nav>
+</div>
+{% endexample %}
+
+### Alignment
+
+Use `.pull-left` or `.pull-right` to align multiple elements within the navbar.
+
+{% example html %}
- <a class="nav-link" href="#">Home</a>
++<nav class="navbar navbar-default">
+ <h3 class="navbar-brand pull-left">
+ <a href="#">Navbar</a>
+ </h3>
+ <ul class="nav nav-pills pull-left">
+ <li class="nav-item active">
- </div>
++ <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Features</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Pricing</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">About</a>
+ </li>
+ </ul>
+ <ul class="nav nav-pills pull-right">
+ <li class="nav-item">
+ <a class="nav-link" href="#">Help</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Sign out</a>
+ </li>
+ </ul>
- <div class="navbar navbar-inverse">
++</nav>
+{% endexample %}
+
+### Inverse color scheme
+
+Replace `.navbar-default` with `.navbar-inverse` for a darker background color and white text.
+
+{% example html %}
- <a class="nav-link" href="#">Home</a>
++<nav class="navbar navbar-inverse">
+ <h3 class="navbar-brand pull-left">
+ <a href="#">Navbar</a>
+ </h3>
+ <ul class="nav nav-pills pull-left">
+ <li class="nav-item active">
- </div>
++ <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Features</a>

+ <form class="form-inline pull-right">
+ <input class="form-control" type="text" placeholder="Search">

+
+Navigation available in Bootstrap share general markup and styles, from the base `.nav` class to the active and disabled states. Swap modifier classes to switch between each style.
+
++## Regarding accessibility
++
++If you are using navs to provide a navigation bar, be sure to add a `role="navigation"` to the most logical parent container of the `<ul>`, or wrap a `<nav>` element around the whole navigation. Do not add the role to the `<ul>` itself, as this would prevent it from being announced as an actual list by assistive technologies.
++
+## Base nav
+
+Roll your own navigation style by extending the base `.nav` component. All Bootstrap's nav components are built on top of this. Includes styles for the disabled state, but **not the active state**.
+
+{% example html %}
- <nav class="nav" role="tablist">
++<ul class="nav">
+ <li class="nav-item">
+ <a class="nav-link" href="#">Link</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Link</a>
+ </li>
+ <li class="nav-item">
+ <a class="nav-link" href="#">Another link</a>
+ </li>
+ <li class="nav-item disabled">
+ <a class="nav-link" href="#">Disabled</a>
+ </li>
+</ul>
+{% endexample %}
+
+Classes are used throughout, so your markup can be super flexible. Use `<ul>`s like above, or roll your own with say a `<nav>` element.
+
+{% example html %}
- Takes the basic nav from above and adds the `.nav-tabs` class to generate a tabbed interface.
++<nav class="nav">
+ <a class="nav-link active" href="#">Active</a>
+ <a class="nav-link" href="#">Link</a>
+ <a class="nav-link" href="#">Another link</a>
+ <a class="nav-link disabled" href="#">Disabled</a>
+</nav>
+{% endexample %}
+
+## Tabs
+
- <ul class="nav nav-tabs" role="tablist">
++Takes the basic nav from above and adds the `.nav-tabs` class to generate a tabbed interface. Use them to create tabbable regions with our [tab JavaScript plugin](../javascript/tabs).
+
+{% example html %}

- <h4>Requires JavaScript tabs plugin</h4>
- <p>For tabs with tabbable areas, you must use the <a href="../javascript/#tabs">tabs JavaScript plugin</a>.</p>

+title: Pagination
+---
+
+Provide pagination links for your site or app with the multi-page pagination component, or the simpler [pager alternative](#pagination-pager).
+
+## Default pagination
+
+Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.
+
+{% example html %}
+<nav>
+ <ul class="pagination">
- <li><a href="#">»</a></li>
++ <li>
++ <a href="#">
++ <span aria-hidden="true">«</span>
++ <span class="sr-only">Previous</span>
++ </a>
++ </li>
+ <li><a href="#">1</a></li>
+ <li><a href="#">2</a></li>
+ <li><a href="#">3</a></li>
+ <li><a href="#">4</a></li>
+ <li><a href="#">5</a></li>
- <li class="disabled"><a href="#">«</a></li>
- <li class="active"><a href="#">1 <span class="sr-only">(current)</span></a></li>
++ <li>
++ <a href="#">
++ <span aria-hidden="true">»</span>
++ <span class="sr-only">Next</span>
++ </a>
++ </li>
+ </ul>
+</nav>
+{% endexample %}
+
+### Disabled and active states
+
+Links are customizable for different circumstances. Use `.disabled` for unclickable links and `.active` to indicate the current page.
+
+{% example html %}
+<nav>
+ <ul class="pagination">
- <li><a href="#">»</a></li>
++ <li class="disabled">
++ <a href="#">
++ <span aria-hidden="true">«</span>
++ <span class="sr-only">Previous</span>
++ </a>
++ </li>
++ <li class="active">
++ <a href="#">1 <span class="sr-only">(current)</span></a>
++ </li>
+ <li><a href="#">2</a></li>
+ <li><a href="#">3</a></li>
+ <li><a href="#">4</a></li>
+ <li><a href="#">5</a></li>
- You can optionally swap out active or disabled anchors for `<span>` to remove click functionality while retaining intended styles.
++ <li>
++ <a href="#">
++ <span aria-hidden="true">»</span>
++ <span class="sr-only">Next</span>
++ </a>
++ </li>
+ </ul>
+</nav>
+{% endexample %}
+
- <li class="disabled"><span>«</span></li>
++You can optionally swap out active or disabled anchors for `<span>`, or omit the anchor in the case of the previous/next arrows, to remove click functionality while retaining intended styles.
+
+{% highlight html %}
+<nav>
+ <ul class="pagination">
- ...
++ <li class="disabled">
++ <span>
++ <span aria-hidden="true">«</span>
++ <span class="sr-only">Previous</span>
++ </span>
++ </li>
+ <li class="active"><span>1 <span class="sr-only">(current)</span></span></li>
- <li><a href="#">«</a></li>
+ </ul>
+</nav>
+{% endhighlight %}
+
+
+### Sizing
+
+Fancy larger or smaller pagination? Add `.pagination-lg` or `.pagination-sm` for additional sizes.
+
+{% example html %}
+<nav>
+ <ul class="pagination pagination-lg">
- <li><a href="#">»</a></li>
++ <li>
++ <a href="#">
++ <span aria-hidden="true">«</span>
++ <span class="sr-only">Previous</span>
++ </a>
++ </li>
+ <li><a href="#">1</a></li>
+ <li><a href="#">2</a></li>
+ <li><a href="#">3</a></li>
- <li><a href="#">«</a></li>
++ <li>
++ <a href="#">
++ <span aria-hidden="true">»</span>
++ <span class="sr-only">Next</span>
++ </a>
++ </li>

++ </li>
+ <li><a href="#">1</a></li>
+ <li><a href="#">2</a></li>
+ <li><a href="#">3</a></li>
- <li class="previous"><a href="#">← Older</a></li>
- <li class="next"><a href="#">Newer →</a></li>
++ <li>
++ <a href="#">
++ <span aria-hidden="true">»</span>
++ <span class="sr-only">Next</span>
++ </a>
++ </li>
+ </ul>
+</nav>
+{% endexample %}
+
+## Pager
+
+Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.
+
+### Default example
+
+By default, the pager centers links.
+
+{% example html %}
+<nav>
+ <ul class="pager">
+ <li><a href="#">Previous</a></li>
+ <li><a href="#">Next</a></li>
+ </ul>
+</nav>
+{% endexample %}
+
+### Aligned links
+
+Alternatively, you can align each link to the sides:
+
+{% example html %}
+<nav>
+ <ul class="pager">
- <li class="previous disabled"><a href="#">← Older</a></li>
- <li class="next"><a href="#">Newer →</a></li>
++ <li class="previous"><a href="#">Older</a></li>
++ <li class="next"><a href="#">Newer</a></li>
+ </ul>
+</nav>
+{% endexample %}
+
+
+### Optional disabled state
+
+Pager links also use the `.disabled` class.
+
+{% highlight html %}
+<nav>
+ <ul class="pager">
++ <li class="previous disabled"><a href="#">Older</a></li>
++ <li class="next"><a href="#">Newer</a></li>
+ </ul>

+
+Bootstrap is built to work best in the latest desktop and mobile browsers, meaning older browsers might display differently styled, though fully functional, renderings of certain components.
+
+### Supported browsers
+
+Bootstrap supports the **latest, stable releases** of all major browsers and platforms. On Windows, **we support Internet Explorer 9-11**. More specific support information is provided below.

+
+### Supporting Internet Explorer 8
+
+As of v4, Bootstrap no longer supports IE8. **If you require IE8 support, we recommend you use Bootstrap 3.** It's still supported by our team for bugfixes and documentation changes, but no new features will be added to it.
+
+Alternatively, you can add the some third party JavaScript to backfill support for the browser. You'll need the following:
+
+* [The HTML5 shiv](http://en.wikipedia.org/wiki/HTML5_Shiv)
+* [Respond.js](https://github.com/scottjehl/Respond)
+* [Rem unit polyfill](https://github.com/chuckcarpenter/REM-unit-polyfill)
+
+### IE Compatibility modes
+
+Bootstrap is not supported in the old Internet Explorer compatibility modes. To be sure you're using the latest rendering mode for IE, consider including the appropriate `<meta>` tag in your pages:
+
+{% highlight html %}
+<meta http-equiv="X-UA-Compatible" content="IE=edge">
+{% endhighlight %}
+
+Confirm the document mode by opening the debugging tools: press <kbd>F12</kbd> and check the "Document Mode".
+
+This tag is included in all of Bootstrap's documentation and examples to ensure the best rendering possible in each supported version of Internet Explorer.
+
+See [this StackOverflow question](http://stackoverflow.com/questions/6771258/whats-the-difference-if-meta-http-equiv-x-ua-compatible-content-ie-edge) for more information.
+
+### Internet Explorer 10 in Windows 8 and Windows Phone 8
+
+Internet Explorer 10 doesn't differentiate **device width** from **viewport width**, and thus doesn't properly apply the media queries in Bootstrap's CSS. Normally you'd just add a quick snippet of CSS to fix this:
+
+{% highlight scss %}
+@-ms-viewport { width: device-width; }
+{% endhighlight %}
+
+However, this doesn't work for devices running Windows Phone 8 versions older than [Update 3 (a.k.a. GDR3)](http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/10/14/introducing-windows-phone-preview-for-developers.aspx), as it causes such devices to show a mostly desktop view instead of narrow "phone" view. To address this, you'll need to **include the following CSS and JavaScript to work around the bug**.
+
+{% highlight scss %}
+@-webkit-viewport { width: device-width; }
+@-moz-viewport { width: device-width; }
+@-ms-viewport { width: device-width; }
+@-o-viewport { width: device-width; }
+@viewport { width: device-width; }
+{% endhighlight %}
+
+{% highlight js %}
+if (navigator.userAgent.match(/IEMobile\/10\.0/)) {
+ var msViewportStyle = document.createElement('style')
+ msViewportStyle.appendChild(
+ document.createTextNode(
+ '@-ms-viewport{width:auto!important}'
+ )
+ )
+ document.querySelector('head').appendChild(msViewportStyle)
+}
+{% endhighlight %}
+
+For more information and usage guidelines, read [Windows Phone 8 and Device-Width](http://timkadlec.com/2013/01/windows-phone-8-and-device-width/).
+
+As a heads up, we include this in all of Bootstrap's documentation and examples as a demonstration.
+
+### Safari percent rounding
+
+The rendering engine of versions of Safari prior to v7.1 for OS X and Safari for iOS v8.0 had some trouble with the number of decimal places used in our `.col-*-1` grid classes. So if you had 12 individual grid columns, you'd notice that they came up short compared to other rows of columns. Besides upgrading Safari/iOS, you have some options for workarounds:
+
+- Add `.pull-right` to your last grid column to get the hard-right alignment
+- Tweak your percentages manually to get the perfect rounding for Safari (more difficult than the first option)
+
- The `.dropdown-backdrop` element isn't used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or any other element which will fire a click event in iOS).
+### Modals, navbars, and virtual keyboards
+
+#### Overflow and scrolling
+
+Support for `overflow: hidden;` on the `<body>` element is quite limited in iOS and Android. To that end, when you scroll past the top or bottom of a modal in either of those devices' browsers, the `<body>` content will begin to scroll.
+
+#### Virtual keyboards
+
+Also, note that if you're using a fixed navbar or using inputs within a modal, iOS has a rendering bug that doesn't update the position of fixed elements when the virtual keyboard is triggered. A few workarounds for this include transforming your elements to `position: absolute;` or invoking a timer on focus to try to correct the positioning manually. This is not handled by Bootstrap, so it is up to you to decide which solution is best for your application.
+
+#### Navbar Dropdowns
+
- Our HTML docs likewise have some trivial and inconsequential HTML validation warnings due to our inclusion of [X-UA-Compatible `<meta>` tags](#ie-compatibility-modes) to avoid Internet Explorer issues and our inclusion of a workaround for [a certain Firefox bug](https://bugzilla.mozilla.org/show_bug.cgi?id=654072).
++The `.dropdown-backdrop` element isn't used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or [any other element which will fire a click event in iOS](https://developer.mozilla.org/en-US/docs/Web/Events/click#Safari_Mobile)).
+
+### Browser zooming
+
+Page zooming inevitably presents rendering artifacts in some components, both in Bootstrap and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.
+
+### Printing
+
+Even in some modern browsers, printing can be quirky.
+
+In particular, as of Chrome v32 and regardless of margin settings, Chrome uses a viewport width significantly narrower than the physical paper size when resolving media queries while printing a webpage. This can result in Bootstrap's extra-small grid being unexpectedly activated when printing. [See #12078 for some details.](https://github.com/twbs/bootstrap/issues/12078) Suggested workarounds:
+
+Also, as of Safari v8.0, fixed-width <code>.container</code>s can cause Safari to use an unusually small font size when printing. See <a href="https://github.com/twbs/bootstrap/issues/14868">#14868</a> for more details. One potential workaround for this is adding the following CSS:</p>
+
+{% highlight css %}
+@media print {
+ .container {
+ width: auto;
+ }
+}
+{% endhighlight %}
+
+### Android stock browser
+
+Out of the box, Android 4.1 (and even some newer releases apparently) ship with the Browser app as the default web browser of choice (as opposed to Chrome). Unfortunately, the Browser app has lots of bugs and inconsistencies with CSS in general.
+
+#### Select menu
+
+On `<select>` elements, the Android stock browser will not display the side controls if there is a `border-radius` and/or `border` applied. (See [this StackOverflow question](http://stackoverflow.com/questions/14744437/html-select-box-not-showing-drop-down-arrow-on-android-version-4-0-when-set-with) for details.) Use the snippet of code below to remove the offending CSS and render the `<select>` as an unstyled element on the Android stock browser. The user agent sniffing avoids interference with Chrome, Safari, and Mozilla browsers.
+
+{% highlight html %}
+<script>

+### Validators
+
+In order to provide the best possible experience to old and buggy browsers, Bootstrap uses [CSS browser hacks](http://browserhacks.com) in several places to target special CSS to certain browser versions in order to work around bugs in the browsers themselves. These hacks understandably cause CSS validators to complain that they are invalid. In a couple places, we also use bleeding-edge CSS features that aren't yet fully standardized, but these are used purely for progressive enhancement.
+
+These validation warnings don't matter in practice since the non-hacky portion of our CSS does fully validate and the hacky portions don't interfere with the proper functioning of the non-hacky portion, hence why we deliberately ignore these particular warnings.
+
++Our HTML docs likewise have some trivial and inconsequential HTML validation warnings due to our inclusion of a workaround for [a certain Firefox bug](https://bugzilla.mozilla.org/show_bug.cgi?id=654072).

+title: Alerts
+---
+
+Add dismiss functionality to all alert messages with this plugin.
+
+## Examples
+
+{% example html %}
+<div class="alert alert-warning alert-dismissible fade in" role="alert">
+ <button type="button" class="close" data-dismiss="alert">
+ <span aria-hidden="true">×</span>
+ <span class="sr-only">Close</span>
+ </button>
+ <strong>Holy guacamole!</strong> Best check yo self, you're not looking too good.
+</div>
+{% endexample %}
+
++When using a `.close` button, it must be the first child of the `.alert-dismissible` and no text content may come before it in the markup.
++
+{% example html %}
+<div class="alert alert-danger alert-dismissible fade in" role="alert">
+ <button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
+ <h4>Oh snap! You got an error!</h4>
+ <p>Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.</p>
+ <p>
+ <button type="button" class="btn btn-danger">Take this action</button>
+ <button type="button" class="btn btn-secondary">Or do this</button>
+ </p>
+</div>
+{% endexample %}
+
+## Usage
+
+Enable dismissal of an alert via JavaScript:
+
+{% highlight js %}
+$(".alert").alert()
+{% endhighlight %}
+
+### Markup
+
+Just add `data-dismiss="alert"` to your close button to automatically give an alert close functionality. Closing an alert removes it from the DOM.
+
+{% highlight html %}
+<button type="button" class="close" data-dismiss="alert">
+ <span aria-hidden="true">×</span>
+ <span class="sr-only">Close</span>
+</button>
+{% endhighlight %}
+
+To have your alerts use animation when closing, make sure they have the `.fade` and `.in` classes already applied to them.
+
+### Methods
+
+#### $().alert()
+
+Makes an alert listen for click events on descendant elements which have the `data-dismiss="alert"` attribute. (Not necessary when using the data-api's auto-initialization.)
+
+#### $().alert('close')
+
+Closes an alert by removing it from the DOM. If the `.fade` and `.in` classes are present on the element, the alert will fade out before it is removed.
+
+{% highlight js %}$(".alert").alert('close'){% endhighlight %}
+
+### Events
+
+Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
+
+<div class="table-responsive">
+ <table class="table table-bordered table-striped">
+ <thead>
+ <tr>
+ <th style="width: 150px;">Event Type</th>

+ <h4>Accessibility issue</h4>
+ <p>The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.</p>
+</div>
+
+## Usage
+
+### Multiple carousels</h3>
+
+Carousels require the use of an `id` on the outermost container (the `.carousel`) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's `id`, be sure to update the relevant controls.
+
+### Via data attributes
+
+Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.
+
+The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load. **It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.**
+
+### Via JavaScript
+
+Call carousel manually with:
+
+{% highlight js %}
+$('.carousel').carousel()
+{% endhighlight %}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.
+
+<div class="table-responsive">
+ <table class="table table-bordered table-striped">
+ <thead>

+ <td>Whether the carousel should react to keyboard events.</td>
+ </tr>
+ </tbody>
+ </table>
+</div>
+
+### Methods
+
+#### .carousel(options)
+
+Initializes the carousel with an optional options `object` and starts cycling through items.
+
+{% highlight js %}
+$('.carousel').carousel({
+ interval: 2000
+})
+{% endhighlight %}
+
+#### .carousel('cycle')
+
+Cycles through the carousel items from left to right.
+
+#### .carousel('pause')
+
+Stops the carousel from cycling through items.
+
+#### .carousel(number)
+
+Cycles the carousel to a particular frame (0 based, similar to an array).
+
+#### .carousel('prev')
+
+Cycles to the previous item.
+
+#### .carousel('next')
+
+Cycles to the next item.
+
+### Events
+
+Bootstrap's carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:
+
+- `direction`: The direction in which the carousel is sliding (either `"left"` or `"right"`).
+- `relatedTarget`: The DOM element that is being slid into place as the active item.
+
+
+<div class="table-responsive">

- Get base styles and flexible support for collapsible components like accordions and navigation.

+title: Collapse
+---
+
- ## Example accordion
++Flexible plugin that utilizes a handful of classes for easy toggle behavior.
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Plugin dependency</h4>
+ <p>Collapse requires the <a href="#transitions">transitions plugin</a> to be included in your version of Bootstrap.</p>
+</div>
+
- Using the collapse plugin, we built a simple accordion by extending the panel component.
++## Example
+
++Click the buttons below to show and hide another element via class changes:
++
++- `.collapse` hides content
++- `.collapsing` is applied during transitions
++- `.collapse.in` shows content
++
++You can use a link with the `href` attribute, or a button with the `data-target` attribute. In both cases, the `data-toggle="collapse"` is required.
++
++{% example html %}
++ <p>
++ <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
++ Link with href
++ </a>
++ <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
++ Button with data-target
++ </button>
++ </p>
++ <div class="collapse" id="collapseExample">
++ <div class="well">

+{% endexample %}
+
+You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.
+
+<div class="bs-callout bs-callout-warning">
+ <h4>Make expand/collapse controls accessible</h4>
+ <p>Be sure to add <code>aria-expanded</code> to the control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of <code>aria-expanded="false"</code>. If you've set the collapsible element to be open by default using the <code>in</code> class, set <code>aria-expanded="true"</code> on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.</p>
+ <p>Additionally, if your control element is targetting a single collapsible element – i.e. the <code>data-target</code> attribute is pointing to an <code>id</code> selector – you may add an additional <code>aria-controls</code> attribute to the control element, containing the <code>id</code> of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.</p>
+</div>
+
+{% highlight html %}
+<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
+ simple collapsible
+</button>
+
+<div id="demo" class="collapse in">...</div>
+{% endhighlight %}
+
+
+## Usage
+
+The collapse plugin utilizes a few classes to handle the heavy lifting:
+
+- `.collapse` hides the content
+- `.collapse.in` shows the content
+- `.collapsing` is added when the transition starts, and removed when it finishes
+
+These classes can be found in `component-animations.less`.
+
+### Via data attributes
+
+Just add `data-toggle="collapse"` and a `data-target` to the element to automatically assign control of a collapsible element. The `data-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element. If you'd like it to default open, add the additional class `in`.
+
+To add accordion-like group management to a collapsible control, add the data attribute `data-parent="#selector"`. Refer to the demo to see this in action.
+
+### Via JavaScript
+
+Enable manually with:
+
+{% highlight js %}
+$('.collapse').collapse()
+{% endhighlight %}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-parent=""`.

+
+## Usage
+
+Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the `.open` class on the parent list item.
+
+On mobile devices, opening a dropdown adds a `.dropdown-backdrop` as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. **This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.**
+
+Note: The `data-toggle="dropdown"` attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.
+
+### Via data attributes
+
+Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.
+
+{% highlight html %}
+<div class="dropdown">
+ <button id="dLabel" type="button" data-toggle="dropdown">
+ Dropdown trigger
+ <span class="caret"></span>
+ </button>
+ <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
+ ...
+ </ul>
+</div>
+{% endhighlight %}
+
+To keep URLs intact with link buttons, use the `data-target` attribute instead of `href="#"`.
+
+{% highlight html %}
+<div class="dropdown">
+ <a id="dLabel" data-target="#" href="http://example.com" data-toggle="dropdown">
+ Dropdown trigger
+ <span class="caret"></span>
+ </a>
+
+ <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
+ ...
+ </ul>
+</div>
+{% endhighlight %}
+
+### Via JavaScript
+
+Call the dropdowns via JavaScript:
+
+{% highlight js %}
+$('.dropdown-toggle').dropdown()
+{% endhighlight %}
+
+<div class="bs-callout bs-callout-info">
+ <h4><code>data-toggle="dropdown"</code> still required</h4>
+ <p>Regardless of whether you call your dropdown via JavaScript or instead use the data-api, <code>data-toggle="dropdown"</code> is always required to be present on the dropdown's trigger element.</p>
+</div>
+
+### Options
+
+*None.*

+
- <td>This event fires immediately when the show instance method is called. The toggling anchor element is available as the <code>relatedTarget</code> property of the event.</td>

+## Varying modal content based on trigger button
+
+Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use `event.relatedTarget` and [HTML `data-*` attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) (possibly [via jQuery](http://api.jquery.com/data/)) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on `relatedTarget`.

+
+## Usage
+
+The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds `.modal-open` to the `<body>` to override default scrolling behavior and generates a `.modal-backdrop` to provide a click area for dismissing shown modals when clicking outside the modal.
+
+### Via data attributes
+
+Activate a modal without writing JavaScript. Set `data-toggle="modal"` on a controller element, like a button, along with a `data-target="#foo"` or `href="#foo"` to target a specific modal to toggle.
+
+{% highlight html %}
+<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
+{% endhighlight %}
+
+### Via JavaScript
+
+Call a modal with id `myModal` with a single line of JavaScript:
+
+{% highlight js %}$('#myModal').modal(options){% endhighlight %}
+
+### Options
+
+Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-backdrop=""`.
+

+
+### Individual or compiled
+
+Plugins can be included individually (using Bootstrap's individual `*.js` files), or all at once (using `bootstrap.js` or the minified `bootstrap.min.js`).
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Using the compiled JavaScript</h4>
+ <p>Both <code>bootstrap.js</code> and <code>bootstrap.min.js</code> contain all plugins in a single file. Include only one.</p>
+</div>
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Component data attributes</h4>
+ <p>Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.</p>
+</div>
+
+<div class="bs-callout bs-callout-danger">
+ <h4>Plugin dependencies</h4>
+ <p>Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included <strong>before</strong> the plugin files). <a href="{{ site.repo }}/blob/v{{ site.current_version }}/bower.json">Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</p>
+</div>
+
+### Data attributes
+
+You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-class API and should be your first consideration when using a plugin.
+
+That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with `data-api`. This looks like this:
+
+{% highlight js %}
+$(document).off('.data-api')
+{% endhighlight %}
+
+Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:
+
+{% highlight js %}
+$(document).off('.alert.data-api')
+{% endhighlight %}
+
++<div class="bs-callout bs-callout-danger">
++ <h4>Only one plugin per element via data attributes</h4>
++ <p>Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.</p>
++</div>
++
+### Programmatic API
+
+We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
+
+{% highlight js %}
+$('.btn.danger').button('toggle').addClass('fat')
+{% endhighlight %}
+
+All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
+
+{% highlight js %}
+$('#myModal').modal() // initialized with defaults
+$('#myModal').modal({ keyboard: false }) // initialized with no keyboard
+$('#myModal').modal('show') // initializes and invokes show immediately
+{% endhighlight %}
+
+Each plugin also exposes its raw constructor on a `Constructor` property: `$.fn.popover.Constructor`. If you'd like to get a particular plugin instance, retrieve it directly from an element: `$('[rel="popover"]').data('popover')`.
+
+#### Default settings
+You can change the default settings for a plugin by modifying the plugin's `Constructor.DEFAULTS` object:
+
+{% highlight js %}
+$.fn.modal.Constructor.DEFAULTS.keyboard = false // changes default for the modal plugin's `keyboard` option to false
+{% endhighlight %}
+
+### No conflict
+
+Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call `.noConflict` on the plugin you wish to revert the value of.
+
+{% highlight js %}
+var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
+$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
+{% endhighlight %}
+
+### Events
+
+Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. `show`) is triggered at the start of an event, and its past participle form (ex. `shown`) is triggered on the completion of an action.
+
+As of 3.0.0, all Bootstrap events are namespaced.
+
+All infinitive events provide `preventDefault` functionality. This provides the ability to stop the execution of an action before it starts.
+
+{% highlight js %}
+$('#myModal').on('show.bs.modal', function (e) {
+ if (!data) return e.preventDefault() // stops modal from being shown
+})
+{% endhighlight %}
+
+### No special fallbacks when JavaScript is disabled
+
+Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use [`<noscript>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript) to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.
+
+<div class="bs-callout bs-callout-warning" id="callout-third-party-libs">
+ <h4>Third-party libraries</h4>
+ <p><strong>Bootstrap does not officially support third-party JavaScript libraries</strong> like Prototype or jQuery UI. Despite <code>.noConflict</code> and namespaced events, there may be compatibility problems that you need to fix on your own.</p>

+## Usage
+
+Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
+
+{% highlight js %}
+$('#myTab a').click(function (e) {

+ $(this).tab('show')
+})
+{% endhighlight %}
+
+You can activate individual tabs in several ways:

+$('#myTab a:last').tab('show') // Select last tab
+$('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed)
+{% endhighlight %}
+
+### Markup
+
+You can activate a tab or pill navigation without writing any JavaScript by simply specifying `data-toggle="tab"` or `data-toggle="pill"` on an element. Adding the `.nav` and `.nav-tabs` classes to the tab `<ul>` will apply the Bootstrap <a href="../components/#nav-tabs">tab styling</a>, while adding the `.nav` and `.nav-pills` classes will apply <a href="../components/#nav-pills">pill styling</a>.

+title: Grid system
+---
+
+Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes [predefined classes](#grid-example-basic) for easy layout options, as well as powerful [mixins for generating more semantic layouts](#grid-semantic).
+
+### Introduction
+
+Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:
+
+- Rows must be placed within a `.container` (fixed-width) or `.container-fluid` (full-width) for proper alignment and padding.
+- Use rows to create horizontal groups of columns.
+- Content should be placed within columns, and only columns may be immediate children of rows.
+- Predefined grid classes like `.row` and `.col-xs-4` are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
+- Columns create gutters (gaps between column content) via `padding`. That padding is offset in rows for the first and last column via negative margin on `.row`s.
+- The negative margin is why the examples below are outdented. It's so that content within grid columns is lined up with non-grid content.
+- Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three `.col-xs-4`.
+- If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
+- Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any `.col-md-` class to an element will not only affect its styling on medium devices but also on large devices if a `.col-lg-` class is not present.
+
+Look to the examples for applying these principles to your code.
+
+### Media queries
+
+We use the following media queries in our Less files to create the key breakpoints in our grid system.
+
+{% highlight scss %}
+/* Extra small devices (phones, less than 768px) */
+/* No media query since this is the default in Bootstrap */
+
+/* Small devices (tablets, 768px and up) */
+@media (min-width: @screen-sm-min) { ... }
+
+/* Medium devices (desktops, 992px and up) */
+@media (min-width: @screen-md-min) { ... }
+
+/* Large devices (large desktops, 1200px and up) */
+@media (min-width: @screen-lg-min) { ... }
+{% endhighlight %}
+
+We occasionally expand on these media queries to include a <code>max-width</code> to limit CSS to a narrower set of devices.
+
+{% highlight scss %}
+@media (max-width: @screen-xs-max) { ... }
+@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... }
+@media (min-width: @screen-md-min) and (max-width: @screen-md-max) { ... }
+@media (min-width: @screen-lg-min) { ... }
+{% endhighlight %}

+
+### Example: Semantic grid mixins
+
+In addition to [prebuilt grid classes](#grid-example-basic) for fast layouts, Bootstrap includes Less variables and mixins for quickly generating your own simple, semantic layouts.
+
+#### Variables
+
+Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.
+
+{% highlight scss %}
+@grid-columns: 12;
+@grid-gutter-width: 1.5rem;
+{% endhighlight %}
+
+#### Mixins
+
+Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.
+
+{% highlight scss %}
+// Creates a wrapper for a series of columns
+.make-row(@gutter: @grid-gutter-width) {
+ margin-left: (@gutter / -2);
+ margin-right: (@gutter / -2);
+ &:extend(.clearfix all);
+}
+
+// Make the element grid-ready (applying everything but the width)
+.make-col(@gutter: @grid-gutter-width) {
+ position: relative;
+ float: left;
+ min-height: 1px;
+ padding-left: (@gutter / 2);
+ padding-right: (@gutter / 2);
+}
+
+// Set a width (to be used in or out of media queries)
+.make-col-span(@columns) {
+ width: percentage((@columns / @grid-columns));
+}
+
+// Get fancy by offsetting, or changing the sort order
+.make-col-offset(@columns) {
+ margin-left: percentage((@columns / @grid-columns));
+}
+.make-col-push(@columns) {
+ left: percentage((@columns / @grid-columns));
+}
+.make-col-pull(@columns) {
+ right: percentage((@columns / @grid-columns));
+}
+{% endhighlight %}
+
+#### Example usage
+
+You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.
+
+See it in action in <a href="http://jsbin.com/qiqet/3/edit">this rendered example</a>.
+
+{% highlight scss %}
+.container {
+ max-width: 60em;
+ .make-container();
+}
+.row {
+ .make-row();
+}
+.content-main {
+ .make-col();
+
+ @media (max-width: 32em) {
+ .make-col-span(6);
+ }
+ @media (min-width: 32.1em) {
+ .make-col-span(8);
+ }
+}
+.content-secondary {
+ .make-col();
+
+ @media (max-width: 32em) {
+ .make-col-span(6);
+ }
+ @media (min-width: 32.1em) {
+ .make-col-span(4);
+ }
+}
+{% endhighlight %}
+
+{% highlight html %}
+<div class="container">
+ <div class="row">
+ <div class="content-main">...</div>
+ <div class="content-secondary">...</div>
+ </div>
+</div>
+{% endhighlight %}
+
+### Example: Stacked-to-horizontal
+
+Using a single set of `.col-md-*` grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns in any `.row`.
+
+{% example html %}
+<div class="row">
+ <div class="col-md-1">.col-md-1</div>
+ <div class="col-md-1">.col-md-1</div>

+</div>
+<div class="row">
+ <div class="col-md-4">.col-md-4</div>
+ <div class="col-md-4">.col-md-4</div>
+ <div class="col-md-4">.col-md-4</div>
+</div>

+
+### Example: Fluid container
+
+Turn any fixed-width grid layout into a full-width layout by changing your outermost `.container` to `.container-fluid`.
+
+{% highlight html %}
+<div class="container-fluid">
+ <div class="row">
+ ...
+ </div>
+</div>
+{% endhighlight %}
+
+### Example: Mobile and desktop
+
+Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding `.col-xs-*` and `.col-md-*` to your columns. See the example below for a better idea of how it all works.
+
+{% example html %}
+<!-- Stack the columns on mobile by making one full-width and the other half-width -->
+<div class="row">
+ <div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
+ <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
+</div>
+
+<!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
+<div class="row">
+ <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
+ <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
+ <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
+</div>
+
+<!-- Columns are always 50% wide, on mobile and desktop -->
+<div class="row">
+ <div class="col-xs-6">.col-xs-6</div>
+ <div class="col-xs-6">.col-xs-6</div>
+</div>
+{% endexample %}
+
++### Example: Mobile, tablet, desktop
+
+Build on the previous example by creating even more dynamic and powerful layouts with tablet `.col-sm-*` classes.
+
+{% example html %}
+<div class="row">
+ <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
+ <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
+</div>
+<div class="row">
+ <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
+ <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
+ <!-- Optional: clear the XS cols if their content doesn't match in height -->
+ <div class="clearfix visible-xs-block"></div>
+ <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
+</div>
+{% endexample %}
+
+### Example: Column wrapping
+
+If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
+
+{% example html %}
+<div class="row">
+ <div class="col-xs-9">.col-xs-9</div>
+ <div class="col-xs-4">.col-xs-4<br>Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
+ <div class="col-xs-6">.col-xs-6<br>Subsequent columns continue along the new line.</div>
+</div>
+{% endexample %}
+
+### Example: Responsive column resets
+
+With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a `.clearfix` and our [responsive utility classes](#responsive-utilities).
+
+{% example html %}
+<div class="row">
+ <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
+ <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
+
+ <!-- Add the extra clearfix for only the required viewport -->
+ <div class="clearfix visible-xs-block"></div>
+
+ <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
+ <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
+</div>
+{% endexample %}
+
+In addition to column clearing at responsive breakpoints, you may need to **reset offsets, pushes, or pulls**. See this in action in [the grid example](../examples/grid/).
+
+{% example html %}
+<div class="row">
+ <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
+ <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
+</div>
+
+<div class="row">
+ <div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
+ <div class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0">.col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0</div>
+</div>
+{% endexample %}
+
+### Example: Offsetting columns
+
+Move columns to the right using `.col-md-offset-*` classes. These classes increase the left margin of a column by `*` columns. For example, `.col-md-offset-4` moves `.col-md-4` over four columns.
+
+{% example html %}
+<div class="row">
+ <div class="col-md-4">.col-md-4</div>
+ <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
+</div>
+<div class="row">
+ <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
+ <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
+</div>
+<div class="row">
+ <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
+</div>
+{% endexample %}
+
+### Example: Nesting columns
+
+To nest your content with the default grid, add a new `.row` and set of `.col-sm-*` columns within an existing `.col-sm-*` column. Nested rows should include a set of columns that add up to 12 or less (it is not required that you use all 12 available columns).
+
+{% example html %}
+<div class="row">
+ <div class="col-sm-9">
+ Level 1: .col-sm-9
+ <div class="row">
+ <div class="col-xs-8 col-sm-6">
+ Level 2: .col-xs-8 .col-sm-6
+ </div>
+ <div class="col-xs-4 col-sm-6">
+ Level 2: .col-xs-4 .col-sm-6
+ </div>
+ </div>
+ </div>
+</div>
+{% endexample %}
+
+### Example: Column ordering
+
+Easily change the order of our built-in grid columns with `.col-md-push-*` and `.col-md-pull-*` modifier classes.
+
+{% example html %}
+<div class="row">
+ <div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
+ <div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
+</div>
