Why it matters

Deaf and hard-of-hearing people, and anyone watching without sound, cannot follow speech in a video without captions.

How to fix it

Add a <track kind="captions"> file. For YouTube or Vimeo embeds, turn on captions in the player settings and check them. (If the captions are burned into the video, ignore this issue.)

<video controls>
  <source src="intro.mp4">
  <track kind="captions" src="intro.en.vtt" srclang="en" label="English" default>
</video>
