A community-driven effort to make digital accessibility easier.

Accessibility of web content requires semantic information about widgets, structures, and behaviors, in order to allow assistive technologies to convey appropriate information to persons with disabilities. This specification provides an ontology of roles, states, and properties that define accessible user interface elements and can be used to improve the accessibility and interoperability of web content and applications. These semantics are designed to allow an author to properly convey user interface behaviors and structural information to assistive technologies in document-level markup. T...

This document provides readers with an understanding of how to use WAI-ARIA 1.1 [WAI-ARIA] to create accessible rich internet applications. It describes considerations that might not be evident to most authors from the WAI-ARIA specification alone and recommends approaches to make widgets, navigation, and behaviors accessible using WAI-ARIA roles, states, and properties. This document is directed primarily to Web application developers, but the guidance is also useful for user agent and assistive technology developers.

The Web Accessibility Initiative's Accessible Rich Internet Applications Suite (WAI-ARIA, or just ARIA) is a set of tools and guidelines for making web content and applications more accessible. Most notably, it includes a suite of attributes we can add to HTML elements to embed in them more semantic information that

Accessible Rich Internet Applications (ARIA) ermöglichen Webentwicklern Webinhalte und Web-Applikationen (insbesondere solche mit Ajax und JavaScript) besser zugänglich für Menschen mit Behinderungen und anderen Einschränkungen zu machen. Zum Beispiel lassen sich mit ARIA Navigations-Landmarken, JavaScript-Widgets, Formular-Hinweise und Fehlermeldungen hinzufügen und Live-Content-Aktualisierungen barrierefrei gestalten.

What do you do when your HTML doesn't communicate the appropriate semantics to screen readers? You use the roles, states, and properties of WAI-ARIA.
