Touché. Indeed, CSS forces one to recognise layouts that may not conform to a layout 'flow' in boxes. In its defence, I suppose recognising this is important, as to make potential box overlaps explicit (which is typically unwanted). CSS also handles a whole lot of things other than layout, which I'm not well informed of layout constraint systems being able to handle. Being a hodgepodge is an advantage, comparable to how its a great advantage that one can invoke any hodgepodge systems task from bash, as one single tool.
