<h3>Setting Up the HTML</h3>
<p>
The tabs in the tabview widget will be represented by a list of
<code><a></code> elements whose <code>href</code> attribute is set to
the id of an <code><div></code> element that contains its content.
Therefore, without JavaScript and CSS, the tabs function as in-page links.

<h3>Progressive Enhancement</h3>
<p>
The markup above will be transformed using both CSS and JavaScript. To account
for the scenario where the user has CSS enabled in their browser but JavaScript
is disabled, the CSS used to style the tabview will be loaded via JavaScript
using the YUI instance's <a href="http://developer.yahoo.com/yui/3/yui#loader">built-in Loader</a>.
Additionally, a small block of JavaScript will be placed in the
<code><head></code> — used to temporarily hide the markup
while the JavaScript and CSS are in the process of loading to prevent the user
from seeing a flash unstyled content.

<h3>ARIA Support</h3>
<p>
Through the use of CSS and JavaScript the HTML for the tabview can be
transformed into something that looks and behaves like a desktop tab control,
but users of screen readers won't perceive it as an atomic widget, but rather
simply as a set of HTML elements. However, through the application
of the
<a href="http://www.w3.org/TR/wai-aria/">WAI-ARIA Roles and States</a>, it is
possible to improve the semantics of the markup such that users of screen
readers perceive it as a tab control.
</p>
<h3>Keyboard Functionality</h3>
<p>
The keyboard functionality for the tabview widget will be provided by the
Focus Manager Node Plugin. The Focus Manager's
<a href="../../api/plugin.NodeFocusManager.html#config_descendants"><code>descendants</code></a>
attribute is set to a value of ".yui-tab>a", so that only one tab in the tabview
is in the browser's default tab flow. This allows users navigating via the
keyboard to use the tab key to quickly move into and out of the tabview. Once
the tabview has focus, the user can move focus among each tab using the left
and right arrows keys, as defined by the value of the
<a href="../../api/plugin.NodeFocusManager.html#config_keys"><code>keys</code></a>
attribute. Lastly, the
<a href="../../api/plugin.NodeFocusManager.html#config_focusClass"><code>focusClass</code></a>
attribute is used to apply a class of <code>yui-tab-focus</code> to the parent
<code><li></code> of each <code><a></code> when it is focused,
making it easy to style the tab's focused state in each of the
<a href="http://developer.yahoo.com/yui/articles/gbs/#gbschart">A-Grade browsers</a>.

<h3>Accessibility Sugar</h3>
<p>
One of the challenges faced by users of screen readers is knowing when you've
left the context of a given control. In the case of this tabview, if it
were adjacent to another ARIA-enabled widget, the user would know they've
left the tabview when the screen reader announces the role of the adjacent
widget. However, if the tabview is sitting alongside standard HTML content, it
would be really difficult for the user to know when they've left the context of
the active panel.
</p>
<p>
One solution to this problem is to add some additional navigation as the last
child of each tab panel that allows the user to move to the previous and next
panel in the tabview. This will not only help alert users of screen readers
that they've reached the end of the tab's panel, but allow <em>all</em>
keyboard users to move more quickly to the next/previous panel. Without this
additionally navigation, keyboard users would typically have to press
shift+tab to navigate back up to the list of tabs to move to the next/previous
tab.
