Web-Animations supports additive animation. There is a usage pattern for additive, where many concurrent animations on the same property run relative to the underlying value. This is a superior technique for simple transitions, in particular when interrupting or reversing. Formerly, one would simply replace an animation with a new one than continued where the previous left off. But if all animations have a destination value of zero, it permits seamless blending and gives beautiful curves, without mutating, all built from more primitive methods.
Others are very excited about what is possible with an advanced timeline. Please help make this happen. Thanks.
