<h1>Using the Button ARIA Plugin</h1>
<div class="exampleIntro">
<p>
The Button ARIA Plugin makes it easy to use the
<a href="http://www.w3.org/TR/wai-aria/">WAI-ARIA Roles and States</a> with the Button
and ButtonGroup controls.
Using the ARIA plugin, Buttons are more interoperable with assistive technologies (AT),
such as screen readers, making them more accessible to users with disabilities.

<a href="http://video.yahoo.com/watch/3608716/9955201">Watch a screen cast of this example
running in Firefox 3 with the NVDA screen reader</a>, to see immediately the benefits that
ARIA provides, or

NVDA</a> to test this example for yourself.
