 - Clicking on the modal "backdrop" will automatically close the modal.
 - Bootstrap only supports one modal window at a time. Nested modals aren't supported as we believe them to be poor user experiences.
 - Modals use `position: fixed`, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You'll likely run into issues when nesting a `.modal` within another fixed element.
-- One again, due to `position: fixed`, there are some caveats with using modals on mobile devices. [See our browser support docs]({{ site.baseurl }}/getting-started/browsers-devices/#modals-and-dropdowns-on-mobile) for details.

 - Lastly, the `autofocus` HTML attribute has no effect in modals. Here's how you can achieve the same effect with custom JavaScript.

 ## HTML5 `[hidden]` attribute
 
-HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](http://purecss.io), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.
