Understanding WCAG 2.2 is the document you actually want to read when you work with the guidelines: for every success criterion it explains the intent, who benefits, and how to meet it. The W3C publishes it as a set of web pages. That works fine at a desk, but not so well on an e-reader, on a plane, or when you want to search the whole thing at once.

What you should know

  • This is an unofficial format conversion, generated automatically from the w3c/wcag repository. The content is unchanged; only the layout has been adapted for PDF and EPUB.
  • It is not the normative version. The Understanding documents are informative explanations and are not required to meet WCAG.
  • Copyright © W3C. The source documents are published under the W3C Document License, which permits copying and distributing them with the original attribution and notices retained. These files are provided on that basis; I claim no ownership of the content.
  • Before relying on anything here, consult the canonical pages at the W3C.
  • The files are regenerated from the repository from time to time; the exact source commit is printed inside each file.
