WCAG Details
What It Is
Web Content Accessibility Guidelines (WCAG) 2.1 is the W3C's technology-agnostic standard for web accessibility. It provides testable success criteria to make content perceivable, operable, understandable, and robust for people with disabilities, using a layered model of principles, guidelines, and levels.
Key Components
- Four POUR principles with 13 guidelines and ~80 success criteria at A/AA/AAA levels.
- Normative success criteria separated from informative techniques.
- Conformance model requires full pages, complete processes, accessibility-supported tech, non-interference.
Why Organizations Use It
- Meets legal benchmarks (ADA, Section 508, EN 301 549, EAA).
- Reduces litigation risk amid rising lawsuits.
- Improves UX, conversion rates, SEO, market reach.
