Video Autoplay on iOS

MUST

MUST: Autoplaying `<video>` needs `muted` and `playsInline` — without both, iOS Safari blocks playback or forces fullscreen.

Apply muted and playsInline to video tags to enable autoplay on iOS

<video autoPlay muted loop playsInline src="/clip.mp4" />

Bad

Good

Why it matters

iOS Safari blocks video autoplay unless the video is muted and has the playsinline attribute. Without these, the video won't play automatically and may open in fullscreen instead.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
