jQuery Mobile is built upon standard, semantic HTML, allowing pages to be accessible to the broadest range of devices possible. For A-Grade browsers, many of the components in jQuery Mobile leverage techniques such as focus management, keyboard navigation, and HTML attributes specified in the W3C's WAI-ARIA specification.
By utilizing these techniques, we do our best to ensure an accessible experience to users with disabilities such as blindness, who may use screen readers (like VoiceOver, on Apple's iPhone device) or other assistive technology to access the web.
While our accessibility implementation is currently a work in progress, we aim to provide a fully accessible suite of components for version 1.0.
