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

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

Constructor

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:

const cats = document.querySelectorAll('.sharedTimelineCat');
const sharedTimeline = new DocumentTimeline({ originTime: 500 });

for (const cat of cats) {
  const catKeyframes = new KeyframeEffect(cat, keyframes, timing);
  const catAnimation = new Animation(catKeyframes, sharedTimeline);
  catAnimation.play(); 
}
