When used correctly, animations improve user perception and memory of your brand, guide user actions, and help users navigate your application—providing context in a digital space.

The Web Animations API is a tool that enables developers to write imperative animations with JavaScript. It was written to underpin both CSS animation and transition implementations and enable future effects to be developed, as well as existing effects to be composed and timed.

While Firefox and Safari have already implemented the full set of spec features, Chromium 84 brings a slew of previously unsupported features to Chrome and Edge enabling cross-browser interoperability.
