Yes CSS is hard, yes declaratively anticipating all the various types of media you may display on and their relative interaction is a nightmare of variables. BUT, that is enough to justify the inversion from using declarative markup to actually writing some procedural code. Write a function to measure the screen, measure the elements on it, and adjust them dynamically at runtime.
