This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The play() method of the Web Animations API's Animation Interface starts or resumes playing of an animation. If the animation is finished, calling play() restarts the animation, playing it from the beginning.





Return value



In the Growing/Shrinking Alice Game example, clicking or tapping the cake causes Alice's growing animation (aliceChange) to play forward, causing her to get bigger, as well as triggering the cake's animation. Two Animation.play()s, one EventListener:

// The cake has its own animation:
var nommingCake = document.getElementById('eat-me_sprite').animate(
  { transform: 'translateY(0)' },
  { transform: 'translateY(-80%)' }   
], {
  fill: 'forwards',
  easing: 'steps(4, end)',
  duration: aliceChange.effect.timing.duration / 2

// Pause the cake's animation so it doesn't play immediately.

// This function will play when ever a user clicks or taps
var growAlice = function() {

  // Play Alice's animation.

  // Play the cake's animation.


// When a user holds their mouse down or taps, call growAlice to make all the animations play.
cake.addEventListener("mousedown", growAlice, false);
cake.addEventListener("touchstart", growAlice, false);
