About Us

digitalaccessible

Independent, plain English guides to digital accessibility: WCAG and its success criteria, color contrast, alt text and screen readers. We explain the rules and how to test them. We are not a law firm, and nothing here is legal advice.

The source of the rules

WCAG is published by the W3C Web Accessibility Initiative. When a page here and the standard ever disagree, the standard wins.
