Accessibility resources

David helpfully shared these resources with Rob and I in an email.

I've copied them here so we can update this list over time:

• ACCDC ARIA Demo (Accessible Lightbox and Pop-ups)
• heydonworks - simple toolbar widget
• The ARIA Role Conformance Matrices
• Visual Aria BookMarkLet by SSB: The Visual ARIA Bookmarklet is a cascading logic program primarily constructed using CSS that allows any sighted person around the world to literally see ARIA usage on any webpage, or to download the source code and embed it within any development project. This too is fully interactive and changes accordingly for all dynamic widgets that map to ARIA 1.1.
