--- layout: page title: Modal --- Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults. **Due to how HTML5 defines its semantics, the `autofocus` HTML attribute has no effect in Bootstrap modals.**
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.
There are some caveats regarding using modals on mobile devices. See our browser support docs for details.
Be sure to add role="dialog"
to .modal
, aria-labelledby="myModalLabel"
attribute to reference the modal title, and aria-hidden="true"
to tell assistive technologies to skip the modal's DOM elements.
Additionally, you may give a description of your modal dialog with aria-describedby
on .modal
.
Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more information.
