Check for Sufficient Colour Contrast
WAVE and the other checkers will alert you if any of your web-page text’s contrast is too low; use WebAIM’s Colour Contrast Checker to come up with colour schemes that will not fail this important test.
Check for Accessibility Violations
- WebAIM’s WAVE Web Accessibility Evaluation Tool
- Enter you page URL and WAVE will check it for accessibility problems.
- Or add the WAVE extension to Firefox or Chrome and quickly check any page you load.
- WAVE is the easiest of these checkers for beginners to use and understand.
- Deque Axe
- A free Chrome plugin
- Catches some issues that WAVE will miss; specializes in HTML semantics.
- ARC (Accessibility Resource Centre) Toolkit
- A free Chrome plugin.
- ARC Toolkit is the most thorough and detailed of these three checkers, it also requires the most coding knowledge to make full use of it.
Remember, automated tools cannot validate the accessibility of your site completely, against all WCAG 2.0 AA criteria; some things can only be evaluated with human attention.

A Good Book
A very accessible accessibility book is Laura Kalbag’s Accessibility for Everyone. Many of you will not feel the need to read the whole book, but anyone should find her discussion of the basic principles, concepts, and techniques of web accessibility to be concise, clear, and reader-friendly.
