media-playback-rate-button

A button that cycles through playback speed rates

Anatomy

<media-playback-rate-button></media-playback-rate-button>

Behavior

Cycles through playback rates on click. The default rate list is [0.2, 0.5, 0.7, 1, 1.2, 1.5, 1.7, 2]. After the last rate, it wraps back to the first. If the current rate isn’t in the list (e.g., set programmatically), the button jumps to the next rate greater than the current one.

Styling

Display the current rate using the data-rate attribute:

media-playback-rate-button::after {
  content: attr(data-rate) "\00D7";
}

Accessibility

Renders a <button> with an automatic aria-label of "Playback rate {rate}" (e.g., "Playback rate 1.5"). Override with the label prop. Keyboard activation: Enter / Space.
