The required markup for a tooltip is only a `data` attribute and `title` on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to `top` by the plugin).

-**Keep tooltips accessible to keyboard and assistive technology users** by only adding them to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). While other HTML elements can be made focusable by adding `tabindex="0"`, this can create annoying and confusing tab stops on non-interactive elements for keyboard users, and most assistive technologies currently do not announce tooltips in this situation. Additionally, do not rely solely on `hover` as the trigger for your tooltips as this will make theme impossible to trigger for keyboard users.
