HTML and CSS Reference
Specifies the primary language of the element's contents.
Set to true for enabling spell and grammar checking on the element's contents.
Inline CSS styling.
Determines if media element is focusable, and the element's order is in the tabbing se-
Advisory information, such as a tooltip.
Custom data type, such as data-myownuse or data-thisappsuse . Used to read and write

its id attribute. You can capture an entire set of media elements in a page, and pinpoint the
specific one you want by its page position, but it's easier just to use id .
If you have more than one media element on possibly different web pages, and you want to
provide the same CSS styling for each, you'll need to assign a class for each, and then use
the class name in your CSS stylesheet.
Being able to drag and drop media elements is a viable web action, so the draggable and
dropzone attributes are useful. So are the accesskey and tabindex attributes if you want
finer control over the element's keyboard access.
The hidden attribute may not seem as viable at first. However, you could use it to remove an
audio or video element from rendering, while still ensuring access to the contents for purposes
that don't depend on immediate reader access.
