What is WCAG?
WCAG is a set of specific standards designed to make the web more accessible to people with disabilities. It is on its third version, updated over the years to account for changes in web-based digital technology, assistive technology, design and development trends, and the growth of the mobile web. It is published by the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI) in collaboration with individuals and organizations within the global accessibility community according to the W3C Process.
