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.
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.
The Web Animations API adds features to {{domxref("document")}} and {{domxref("element")}}.
