Accessibility Resources for Developers
The following resources are those that I personally have found helpful in my own work. I’m always open to additional resources, so please contact me if you have any to suggest.
Testing tools that I like
WAVE Accessibility Tool (both Chrome and Firefox extensions can be found here.
aXe by Deque (fantastic testing tool with plugins for Chrome and Firefox. Also, an open source library that can be embedded into testing frameworks).
Favelets by Jim Thatcher (bookmarklets for conducting quick accessibility tests. Note, these do not work over HTTPS connections).
Development and jQuery Examples
Paul J. Adam demos (fantastic widgets with implementation examples).
Accessible jQuery UI Components Demonstration (more widgets with implementation examples).
The Incredible Accessible Modal (just exactly what it says, a simple modal with a great implementation).
Adobe’s Accessible Mega-menu (a menu implementation that I really like because it allows paragraphical text to be read within the menu).
Deque University widgets (this portion is in beta, but a comprehensive collection of widgets, I especially like the Live Region Playground).
Making your iOS App Accessible (fantastic resource for iOS accessibility provided by Apple).
Native Accessibility APIs (Direct links to Apple iOS/OSX and Android accessibility API documentation).
