 The `.disabled` class will give buttons a faded appearance. The class is a purely visual style, and won't actually disable a control. For `<button>` elements, you can add the `disabled` attribute to both disable and style it. If you want to disable a link, you should add the `aria-disabled` attribute to mark it as disabled for assistive technology.
