{{ APIRef("Web Animations") }}

The AnimationTimeline interface of the Web Animations API represents the timeline of an animation. This interface exists to define timeline features (inherited by {{domxref("DocumentTimeline")}} and future timeline types) and is not itself directly used by developers. Anywhere you see AnimationTimeline, you should use DocumentTimeline or any other timeline type instead.

Instance properties

• {{domxref("AnimationTimeline.currentTime")}} {{ReadOnlyInline}}
