The WCAG 2.0 (Web Content Accessibility Guidelines) checklist is developed by WebAIM, and is their interpretation of the WCAG 2.0 guidelines and success criteria. Unlike the WCAG 2.0 checklist, the guidelines cover a broad range of web content, and it not technology specific. The checklist provided here, offers recommended techniques for implementing HTML-related principles for WCAG 2.0 conformance.
The checklist utilizes P.O.U.R. (Perceivable, Operable, Understandable, and Robust) to categorizes the different elements of accessibility. Following the recommendation in this checklist is recommended to make sure your HTML-based web applications are conforming to the WCAG 2.0 guidelines.
