Web Accessibility - WCAG Compliance

Last modified on 2022/05/28 10:56

Web Content Accessibility Guidelines (WCAG) 2.0 defines how to make Web content more accessible to people with disabilities.

Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities. Although these guidelines cover a wide range of issues, they are not able to address the needs of people with all types, degrees, and combinations of disability. 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.

WCAG 2.0 is developed through the W3C process in cooperation with individuals and organizations around the world, with a goal of providing a shared standard for Web content accessibility that meets the needs of individuals, organizations, and governments internationally.

Each criteria can have one of the 3 following statuses:

  • Supports: all applicable tests are successful;
  • Supports with Exceptions: an applicable test is failed, at least;
  • Not Applicable: there is no content relevant to the criteria
