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 DocumentTimeline interface of the the Web Animations API represents animation timelines, including the default document timeline (accessed via Document.timeline).

Constructor

DocumentTimeline.DocumentTimeline()
Creates a new DocumentTimeline object associated with the active document of the current browsing context.

Properties

This interface inherits its property from its parent, AnimationTimeline.

AnimationTimeline.currentTime
Returns the time value in milliseconds for this timeline or null if it is inactive.

Examples

We could share a single documentTimeline among multiple animations, thus allowing us to manipulate just that group of animations via their shared timeline. This bit of code would start all the cats animating 500 milliseconds into their animations:

var cats = document.querySelectorAll('.sharedTimelineCat');
cats = Array.prototype.slice.call(cats);

var sharedTimeline = new DocumentTimeline({ originTime: 500 });

cats.forEach(function(cat) { 
  var catKeyframes = new KeyframeEffect(cat, keyframes, timing);
  var catAnimation = new Animation(catKeyframes, sharedTimeline);
  catAnimation.play(); 
});
