โš ๏ธ W3C Working Draft Notice

WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editorsโ€™ draft, which also includes exploratory provisions.

developing Supplemental requirement

Sign Language Controllable

Group: images-and-media • Guideline: sign-language

Summary in Plain English

There is a way to show and hide sign language interpretation, unless it is burned into the video or supplied as a separate interpreted version.

Why It Matters

An interpreter window occupies part of the picture. Viewers who do not use it need it out of the way, and viewers who do need it present.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/images-and-media/sign-language/sign-language-controllable.md.

Except when

  • Sign language interpretation is hard-coded into the video content.
  • A sign language interpreted version is provided as a separate video.

Examples from the Draft

Worked examples the W3C editors wrote into the provision itself, not examples invented here.

Hard-coded sign language interpretation would include video content where the interpreter is standing next to the speaker in the video.
