Overview of ARIA Roles
ARIA is a set of HTML attributes that make web content more accessible to users of assistive technologies, such as screen readers and refreshable braille displays.
This representation of ARIA roles is intended to be a reference for web developers and designers. The roles are categorized by abstract role. Each role is a link that will take you to a page with more information about the role.
This reference guide is based on the WAI-ARIA 1.2 Recommendation(opens in new window)
