No, it has a 3d engine, one that you can happily ignore 99.9999% of the time. CSS has a few gotcha, a few things to got to understand about it (selectors, selector priority and the way content flow depending on absolute / relative positionning), but it is not an impossible language to pick up, far from it.

As the grandparent comment said, don't let the perfect be the enemy of the good.
