Web Accessibility

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

• WCAG 2.1 - these can be confusing, so try the IITAA Techniques.
• IITAA Techniques - easy-to-follow instructions on how to meet WCAG 2.1 for web developers.

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.

• Introduction to ARIA - read this before you do anything with ARIA.
• ARIA Authoring Practices Guide - instructions, patterns, and examples. Use it early & often!
• ARIA 1.2 - the full specification for web accessibility experts. (Coming soon: ARIA 1.3)

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