  The Accessibility Guidelines Working Group ( AG WG ) published   Web Content Accessibility Guidelines (WCAG) 2.2   as a W3C Recommendation. WCAG and supporting documents explain how to make content more accessible to people with disabilities. For an introduction to WCAG, see the  WCAG 2 Overview . WCAG 2.2 adds 9 requirements (called success criteria) since WCAG 2.1. These success criteria improve accessibility for people with visual, physical, and cognitive disabilities. For example, they expand guidance for touch input. To learn more about WCAG 2.2, see   What's New in WCAG 2.2 .
