GNOME3 is already using GNOME Shell, which in return uses gjs and a CSS tree for all its components and layouts? I mean, the GTK layout tree is obviously different than a pure CSS layout tree, but it's been there for already 14+ years...and everyone was complaining about it. You can literally use animations and transitions from the CSS/SVG specification. You also can use "Looking Glass" which is their integrated debugger for layouts.
