Web Content Accessibility Guidelines (WCAG) 2.0
The Web Content Accessibility Guidelines (WCAG) 2.0, developed by the Web Accessibility Initiative (WAI) working group of the World Wide Web Consortium (W3C), define how to make Web content more accessible to people with disabilities. Disability may involve visual, auditory, physical, speech, cognitive, language, learning, and neurological impairments. These guidelines also make Web content more usable by older individuals with changing abilities due to aging and often improve usability for users in general. Although the guidelines cover a wide range of issues, they are unable to address the needs of people with all types, degrees, and combinations of disability.
