Accessible Javascript with and without WAI ARIA
The document discusses making JavaScript accessible. It states that JavaScript content should be at least as accessible without JavaScript, nothing should be withheld from non-JavaScript users, and assistive technologies should be able to use the page. It emphasizes that websites must work without JavaScript first, and that CSS should not be used for interaction or hiding content. The document then introduces WAI-ARIA as a way to add semantics and meaning to elements for screen readers through roles, properties, and live regions. It encourages using WAI-ARIA but also not relying on it exclusively.
