Web Content Accessibility Guidelines (WCAG)

Meaning

Web Content Accessibility Guidelines (WCAG) 2.1 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.

WCAG is based on four main guiding principles of accessibility known by the acronym POUR perceivable, operable, understandable, and robust.

Background

Web Content Accessibility Guidelines (WCAG) 2.1 covers many recommendations for making Web content more accessible.

The Web Content Accessibility Guidelines are part of a series of web accessibility guidelines published by the Web Accessibility Initiative of the World Wide Web Consortium, the main international standards organization for the Internet.

Following these guidelines will make content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations. Still, it will not address every user need for people with these disabilities.
