The Web Animations API is part of a new web standard, currently under development by browser engineers from Mozilla and Google.
We’re excited to see Mozilla have now shipped their implementation of element.animate() in Firefox 48, enabling true cross-browser accelerated animations using this emerging JS API. Google and Mozilla have worked hard together to make sure our implementations are interoperable. This has truly been a collaborative effort!
The benefits in using the Web Animations API can include faster frame-rate with lower power consumption which translates to a better user experience on all devices, especially mobile.
