Web developers increasingly use client-side scripts to create user interface controls that cannot be created with HTML alone. They also use client-side scripts to update sections of a page without requesting a completely new page from a web server. Such techniques on websites are called rich Internet applications. These user interface controls and content updates are often not accessible to users with disabilities, especially screen reader users and users who cannot use a mouse or other pointing device. WAI-ARIA allows web pages (or portions of pages) to declare themselves as applications rather than as static documents, by adding role, property, and state information to dynamic web applications. ARIA is intended for use by developers of web applications, web browsers, assistive technologies, and accessibility evaluation tools.
WAI-ARIA describes how to add semantics and other metadata to HTML content in order to make user interface controls and dynamic content more accessible. For example, with WAI-ARIA it is possible to identify a list of links as a navigation menu and to state whether it is expanded or collapsed. Although originally developed to address accessibility issues in HTML, the use of WAI-ARIA is not limited to HTML: in principle, it can also be used in other markup languages such as Scalable Vector Graphics (SVG).
- Accessible Rich Internet Applications (WAI-ARIA) Version 1.0
- This is primarily aimed at developers of Web browsers, assistive technologies, and other user agents, in addition to developers of other technical specifications, and developers of accessibility evaluation tools. The WAI-ARIA has been marked as completed on 20 March 2014 and is therefore a W3C recommendation.
- WAI-ARIA Overview
- This is a technical introduction to WAI-ARIA. It describes the problems WAI-ARIA tries to address, the underlying concepts, the technical approach and business reasons for adopting WAI-ARIA.
- WAI-ARIA Best Practices
- This document describes best practices for delivering rich Internet applications with WAI-ARIA: it discusses subjects such as general steps for building accessible widgets, keyboard navigation, relationships, form properties, drag-and-drop support, alert and dialog boxes, reusable component libraries, and testing.
