> Flash could also do 3D animation, which CSS cannot

Saw a few Codepens over the years[0] where people managed to rotate 3D cubes, all done entirely with CSS. Of course if you needed to interact with the cube you would need JS, but 3D can be achieved with CSS alone, it's just a very hacky way of doing it.

This is a CSS only 3d thing I did a while ago as an exercise. Its a bit buggy but still pretty neat https://jaygles.github.io/city-block/

You can do interactions with hover, [hidden] check boxes, focus and even anchors.
