About
The Web Content Accessibility Guidelines (WCAG) are an international standard developed by the W3C that defines how to make web content, including text and media, accessible to people with disabilities.
They are technology-agnostic and structured around four core principles (perceivable, operable, understandable, and robust) and define testable success criteria with three conformance levels (A, AA, AAA) used to evaluate accessibility compliance.
