Description : Most JavaScript toolkits offer a library of client-side widgets that mimic the behaviour of familiar desktop interfaces. Sliders, menu bars, file list views, and more can be built with a combination of JavaScript, CSS, and HTML. But the current HTML spec is limited to simple tags such as forms, buttons, lists, and the like.
For more sophisticated interfaces, generic tags such as <span> and <div> rarely provide sufficient semantics to make the widget comprehensible to assistive technologies. Most hand-rolled DHTML widgets don't work consistently like their desktop counterparts, and keyboard navigation is often ignored completely or limited to tedious Tab-key based modes.
