Guidelines/W3

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. This version adds features new since WAI-ARIA 1.0 [wai-aria-1.0] to improve interoperability with assistive technologies to form a more consistent accessibility model for [html5] and [SVG2]. This specification complements both [html5] and [SVG2].

This specification defines the authoring rules (author conformance requirements) for the use of Accessible Rich Internet Applications (WAI-ARIA) 1.1 and Digital Publishing WAI-ARIA Module 1.0 attributes on [HTML] elements. This specification's primary objective is to define requirements for use with conformance checking tools used by authors (i.e., web developers). These requirements will aid authors in their development of web content, including custom interfaces/widgets, that makes use of ARIA to complement or extend the features of the host language [HTML].

Introduces the Web Content Accessibility Guidelines (WCAG) international standard, including WCAG 2.0, WCAG 2.1, and WCAG 2.2. WCAG documents explain how to make web content more accessible to people with disabilities.

This document provides readers with an understanding of how to use WAI-ARIA 1.2 [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.
