WCAG
Web Content Accessibility Guidelines (WCAG) are a set of international standards published by the W3C Web Accessibility Initiative (WAI) for making web content accessible to people with disabilities. WCAG covers a wide range of recommendations across four principles (Perceivable, Operable, Understandable, Robust), with conformance levels A, AA, and AAA. WCAG 2.2 (ISO/IEC 40500:2025) is the current standard, while WCAG 3.0 is in active development targeting broader coverage of websites, mobile apps, VR environments, and digital documents.
