Making the Web Accessible

Strategies, standards, and supporting resources to help you make the Web more accessible to people with disabilities.


The World Wide Web Consortium (W3C) develops international standards for the Web: HTML, CSS, and many more.


The W3C Web Accessibility Initiative (WAI) develops standards and support materials to help you understand and implement accessibility.


You can use W3C WAI resources to make your websites, applications, and other digital creations more accessible and usable to everyone.


W3C WAI Website and Resources Redesigned

The redesigned W3C WAI website makes it easier to get information to help you improve web accessibility. The visual design, information architecture, navigation, and overall user experience is all new. Much of the content is revised, and we plan to revise more in the coming months. The redesign makes it easier to skim pages, read content, find specific information, and discover new resources. It’s also easier for the community to be involved in improving resources. Please see W3C WAI Website Redesign Information for:

Wide review: Accessible Name and Description Computation

The ARIA WG has published a wide review draft of Accessible Name and Description Computation 1.1. This document describes how user agents determine the names and descriptions of accessible objects, where information comprising that name can come from various characteristics of the content, in order to lead to a consistent result across implementations. The document previously included Accessibility API Mappings, which have been moved to Core Accessibility API Mappings, so this document only describes the procedure to determine accessible name and description, not how to expose it. Please comment by 13 April 2018.


Personalization Semantics Explainer and Content module updated

The ARIA WG has published an updated draft of Personalization Semantics Explainer 1.0 and Personalization Semantics Content Module 1.0. The explainer adds a Vocabulary Identification section, does some changes in sections of WAI-ARIA and HTML Microdata, also replaces the RDFa section with editor’s note. The Content module removes aui prefixes from property names, changes some examples and adds some editor’s note in the document. Please comment by 13 April 2018.


For Review: ACT Rules Format 1.0 Working Draft

An updated Working Draft of Accessibility Conformance Testing (ACT) Rules Format is available for review. This draft addresses all comments received on the previous draft. Most importantly, the “Selector” approach was replaced with “Applicability” and “Expectation” pairs, to make ACT Rules less procedural. This draft is accompanied by sample ACT Rules that implement this rules format. Please submit any comments, especially comments related to implementation experience, as soon as possible, before 5 April 2018.

Web Accessibility Perspectives: Keyboard Compatibility

All functionality must be usable with the keyboard. That is, users can access links, buttons, forms, and other controls using the Tab key and other keystrokes. Websites should not require a mouse.

Keyboard accessibility is essential for people with disabilities and benefits everyone in a variety of situations.

Featured Resource: Accessibility Principles

The Accessibility Principles page introduces some of the web accessibility requirements for websites, web applications, browsers, and other tools. It provides references to the international standards from W3C Web Accessibility Initiative (WAI) and to stories of web users.
