A new animation library, built on the Web Animations API for the smallest filesize and the fastest performance.
For fairly basic animations, this might provide an attractive alternative to the heavier Greensock. The Motion docs do however flag the limitation that it can only animate “CSS styles”. They also say “SVG styles work fine”. I hope by this they mean SVG presentation attributes rather than inline CSS on an SVG, although it’s hard to tell. However their examples look promising.
The docs website also contains some really great background information regarding animation performance.
