WCAG 2.2 + ARIA reference
A working reference, not the spec itself. 86 WCAG 2.2 success criteria and 68 ARIA roles, states, and properties — each with a plain-language summary, how-to-meet notes, the failures we see most often in audits, and a direct link to the W3C source. Built to be cited from a PR comment or pasted into an a11y review without leaving an attribution trail.

How to use this reference
- Each entry is summarised in plain language — what the rule is, who it helps, and how to satisfy it. The W3C source is one click away when you need the exact normative wording.
- "Common failures" reflect what we see in audits — drawn from QualiBooth, axe, and Lighthouse reports across roughly 500 production sites in 2025-26. They are not a substitute for the W3C "Failures of …" documents but a faster route to the issues authors hit most often.
- Cite us without hostage — every page exposes JSON-LD and a printable URL; nothing requires login, JavaScript, or an account. Link the SC page in a PR comment and the reviewer lands on the same view you did.
