Is that because of epub3 or because of CSS 3? Supporting an epub3 structure doesn't immediately mean supporting all fancy CSS 3 properties (or javascript). Support for CSS 3 can be added even to an epub2 reader. The problem is (I guess) that it's far from trivial, which is why a browser engine is usually employed.
I'd start with the "basics", and ask for vh, vw, flex and grid support, that should keep many people busy for long enough
