The Web Accessibility Initiative (WAI) is the organization that manages—among other things—the Web Content Accessibility Guidelines designed to make websites more accessible.
As you might expect from the name, “How to Meet WCAG 2.0” is a free online tool put together by WAI which aims to help web developers ensure that their web sites meet the guidelines.
The tool is essentially a version of the full guidelines which also contains methods developers allows the user to filter by compliance level, technologies used (e.g. HTML strategies vs CSS strategies), and by type of design (developing; interaction design; content design; visual design). By selecting or deselecting one of these filters, the user is able to limit what shows on the list of guidelines and see specific strategies they might use to ensure that their site meets the WCAG 2.0 guidelines.
Given that the guidelines have a reputation of being hard to understand, this tool should make designing accessible web sites—or updating inaccessible ones—easier for non-expert web developers.
“How to Meet WCAG 2.0” is available for free on the WAI website, and knowledgeable users are also invited to contribute by reporting bugs, contributing to the tool on GitHub, or adding new WCAG techniques.
