## Autoplaying video

Passing looks like: No video starts playing automatically.

**Why it matters.** Autoplaying video downloads megabytes before the visitor asked for anything, drains phone batteries and makes the page move while people try to read it.

**How to fix it.**

1. Remove the autoplay attribute and show a poster image with a play button instead.
2. If a background video must autoplay, keep it muted, under 1 MB and use prefers-reduced-motion to disable it.
