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.
