The Web Animations API allows for synchronizing and timing changes to the presentation of a Web page, i.e. animation of DOM elements. It does so by combining two models: the Timing Model and the Animation Model.

Concepts and usage

The Web Animations API provides a common language for browsers and
developers to describe animations on DOM elements. To get more
information on the concepts behind the API and how to use it, read Using the Web Animations API.

Web Animations interfaces

Provides playback controls and a timeline for an animation node or source. Can take an object created with the
KeyframeEffect()
constructor.
Describes sets of animatable properties and values, called keyframes and their timing options. These can then be played using the
Animation()
constructor.
Represents the timeline of animation. This interface exists to define timeline features (inherited by
DocumentTimeline
and future timeline objects) and is not itself accessed by developers.
Actually part of CSS Animations.
Represents animation timelines, including the default document timeline (accessed using the
Document.timeline
property).
all accept an optional dictionary object of timing properties.

document

.
