1.4.2 Audio Control

오디오 제어

Summary

Audio that plays automatically for more than three seconds must be stoppable or independently adjustable. Background sound drowns out a screen reader's speech output. The safest approach is simply not to autoplay at all.

Common failures

  • Playing background music on page load with no way to stop it.
