Media plays automatically

Why it matters

Sound that starts by itself fights with screen readers and can be impossible to stop. Moving video is also distracting for people with attention or vestibular difficulties.

How to fix it

Remove autoplay, or make sure the video is muted, short and has a visible pause button.

<!-- Before -->
<video autoplay loop src="hero.mp4"></video>

<!-- After -->
<video controls muted src="hero.mp4"></video>
