Failing these makes content unusable for some people.\n- Level AA - the widely required standard. Most laws, regulations, and contracts that reference WCAG require Level AA, which includes everything in Level A.\n- Level AAA - the strictest level. Valuable where achievable, but not expected across an entire website.\n\nWhen someone says a website must "meet WCAG 2.2 AA", they mean it should satisfy every Level A and Level AA criterion in WCAG version 2.2. Silktide allows you to filter accessibility results by level so you can focus on the standard that applies to you.\n\n## Learn more\n\n- Understanding Conformance - how the W3C defines levels and conformance\n- \n
