Web Content Accessibility Guidelines (WCAG) are part of a series of Web accessibility guidelines published by the W3C’s Web Accessibility Initiative. They consist of a set of guidelines for making content accessible, primarily for disabled users, but also for all user agents, including highly limited devices, such as mobile phones. The current version, 2.0, is also an ISO standard, ISO/IEC 40500:2012.
Web Content Accessibility Guidelines (WCAG) is developed through the W3C process in cooperation with individuals and organizations around the world, with a goal of proving a single shared standard for web content accessibility that meets the needs of individuals, organizations, and governments internationally.
The WCAG documents explain how to make web content more accessible to people with disabilities. Web “content” generally refers to the information in a web page or web application, including:
=> natural information such as text, images, and sounds
=> code or markup that defines structure, presentation, etc.
WCAG is primarily intended for:
=> Web content developers (page authors, site designers, etc.)
=> Web authoring tool developers
=> Web accessibility evaluation tool developers
=> Others who want or need a standard for web accessibility
Related resources are intended to meet the needs of many different people, including policy makers, managers, researchers, and others.
