<h1>Using the Container ARIA Plugin</h1>
<div class="exampleIntro">
<p>
The Container 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 Container
family of controls.
Using the ARIA plugin, Dialogs, Alerts and Tooltips created using the Container family are
more interoperable with assistive technologies (AT), such as screen readers, making them more
accessible to users with disabilities.

running in Firefox 3 with the NVDA screen reader</a>, to see immediately the benefits that
ARIA provides, or
