esigning and developing with accessibility in mind has numerous benefits: it makes your website usable by everyone, it makes your content inherently more search engine friendly, and it makes providing context-sensitive interfaces (e.g. mobile) even easier. In this session, Aaron Gustafson will provide you with a quick refresher on progressive enhancement and show you where the Web Accessibility Initiative's Accessible Rich Internet Applications (WAI-ARIA) spec fits into it all. Throughout the talk, Aaron will provide numerous examples of how to weave ARIA into your projects and how to use ARIA, in concert with JavaScript, to dramatically enhance the usability of client-side widgets.
