This is really cool! It’d be even better if you added “playsinline” attributes to your video elements so your videos didn’t play in fullscreen on iPhones.
That should have stopped happening in iOS 11.4. If you’ve upgraded to-or-past that and you’re still seeing that happen, please let me know: email in profile or @jernoble on Twitter.
Interesting. At 1.10 cars per household, and 2.26 people per household, about 47% of SF residents own cars. (Though subtracting out the under-18 population means 55% of driving-age residents own a car.) Also, given there must be some people who own more than one, the actual percentage is probably lower. Still, that's a lower number than I imagined.
The options are: "Allow all Auto Play", "Stop Media with Sound" (the default), and "Never Auto Play".
Site authors following the best practices section in the WebKit.org blog should provide a play button for video-backed-gifs when "Never Auto Play" causes automatic playback to block.
