WCAG
WCAG is an international set of standards created by the World Wide Web Consortium
(W3C) to make web content more accessible to people with disabilities - including
people who are blind, deaf, have limited mobility, cognitive impairments, or other
challenges.
The WCAG guidelines help developers, designers, and content creators build websites
and apps that are usable by everyone. The abbreviation, POUR, is a way of remembering
the main principles of accessibility.
- (P)erceivable: Users must be able to perceive the content with their senses (sight, hearing, touch). Content must not be invisible to any of their senses. Covers sections 1.1-1.4.
- (O)perable: Users must be able to operate navigation and controls (e.g., buttons, links, forms) without barriers. Covers sections 2.1-2.5.
- (U)nderstandable: Content must be clear and easy to understand. Websites should behave in predictable ways. Covers sections 3.1-3.3.
- (R)obust: Content must work reliably with different technologies, including assistive tools like screen readers or voice recognition software. Covers section 4.1.
