UAAG

A set of guidelines from the W3C Web Accessibility Initiative that explains how to make user agents — browsers, media players, and other applications that render web content — accessible to people with disabilities. UAAG addresses how user agents should support assistive technologies, provide accessible built-in functionality, and allow users to customise their experience. Together with WCAG (for web content) and ATAG (for authoring tools), UAAG forms part of the WAI three-pillar model for comprehensive web accessibility.
