Abstract

This document records all known errors in the Web Content Accessibility Guidelines (WCAG) 2.1 specification.

The errata are numbered, classified as Substantive or Editorial, and listed in reverse chronological order of their date of publication in each category.

Each entry has the following information:

A unique entry number
The date it was added to the errata page.
The section referred to.
A description of the problem and correction if applicable.
A rationale for making the change (not required for editorial errata).

Substantive corrections are proposed by the Accessibility Guidelines Working Group, which has consensus that they are appropriate; they are not to be considered normative until a new Recommendation is published following the process to revise a Recommendation.
