This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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








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, 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);
