Web Accessibility

Illinois follows the World Wide Web Consortium (W3C)'s Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. For more information, see:

• Introduction to Web Accessibility - a quick overview from WebAIM.
• IITAA Techniques - how to meet WCAG in terms that web developers should understand.
• WCAG 2.1 - the complete guidelines from the W3C. These can be difficult to digest, so try the resources above before going here.

The Accessible Rich Internet Applications (ARIA) guidelines provide advanced techniques for making custom web components accessible. With ARIA, almost anything is possible, but it's not easy. And with great power comes great responsibility!

• Introduction to ARIA - read this before you do anything with ARIA!
• ARIA Authoring Practices Guide - instructions, patterns, and examples. Don't use ARIA without referring to this guide.
• ARIA 1.2 - the full specification for web accessibility experts. (ARIA 1.3 is coming soon.)

There's a lot you can do to test websites and applications for accessibility without being an accessibility expert. For instructions and tools, visit:
