WCAG overview

The Web Content Accessibility Guidelines (WCAG) 2.2 are a set of recommendations designed to make web content more accessible to people with disabilities.

These guidelines are aimed at improving the user experience for people with various impairments, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

Main principles

WCAG 2.2 is organised around 4 principles, often summarised by the acronym POUR.

Perceivable

Information and user interface components must be presented in ways that users can perceive. This means content should be available to at least one of a user's senses (sight, hearing, touch).

Operable

User interface components and navigation must be operable. Users should be able to use and interact with the interface effectively.

Understandable

Information and the operation of user interface must be understandable. Users should be able to comprehend the information, as well as how to use the interface.

Robust

Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies. This means ensuring compatibility as technologies evolve.

Criteria

You can read all the criteria for WCAG 2.2 on the WCAG 2.2 criteria page.
