If we added this, it would indeed extend the `` grammar, so @larsenwork's example syntax (the timing function on its own, comma-separated from the two surrounding color-stops) is indeed how...

My concern is just whether the midpoint approach can give a decent-looking "soft fade", not whether it can reproduce any particular mathematical definition. It appears to be good enough for...

"Single timing function crossing all the stops" is not how animations work right now; when you supply an `animation-timing-function`, it just sets the default for all the keyframes' individual timing...

Yeah, this is about movement specifically; while there are probably variants of motion blur that can do stuff with color, the traditional and widely-understood definition involves tracking how a given...

I'm assuming we'd just have a "none" (the default) and a "please, if you can" value, with the latter being defined by a general description but leaving the precise details...
