[v4] animation-range and animation-timeline

[bobbymannino]

In v4 there is a lot of syntax for future css and it is awesome i love it, but what is missing is css scroll based animations, you can use your own animate-fade-in-up: fade-in-up linear both but you cannot set animation range or timeline, or i am just missing it, this would be a great feature to have in v4 before its initial release.

Syntax could be something like timeline-view-block range-from-entry-0% range-to-entry-100%?

Edit: im aware you can add it as a utility but i mean baked in
