Features

• Add classes for styling for:

  • radiostar-enhanced (component initialized)
  • radiostar-muted
  • radiostar-playing
  • radiostar-paused
  • radiostar-ended

• Only start playing when the video is visible in the viewport with data-visible-autoplay (via IntersectionObserver) Make sure you leave off the autoplay attribute in your markup.

  • Optionally conditional on media query, e.g. data-visible-autoplay="(min-width: 48em)
  • The muted attribute is required when using this feature.
  • Don’t use the autoplay attribute.
• Automatically pause video when it scrolls out of view (via IntersectionObserver)
• Works as expected with preload="none".
• Sets preload="none" when SaveData is true.
• Disables autoplay when prefers-reduced-motion is enabled
• Use your own external mute/play/pause controls by adding data-mute, data-play, or data-pause respectively to one or more <button> elements.
• iOS note: as of iOS version 14.4, even if you use <track default> iOS will not display captions by default unless it is enabled in Settings. Go to Settings -> Accessibility -> Subtitles & Captioning -> and make sure the Closed Captions + SDH option is selected.
