  When the webkit-playsinline property is specified, Safari on iPhone allows videos to play inline. Videos without the property will commence playback in fullscreen, but users can pinch close on the video to continue playing the video inline.
  On iOS, videos without audio tracks or with disabled audio tracks can play automatically when the webpage loads.

This allows for inline videos in Safari on iOS. Previously, webkit-playsinline only worked for pages saved to the home screen.

This was a 'wow' moment for me, as someone innovating in video.
