I have a DIV container with several inner DIVs layed out by floating them all left. The inner DIVs may change width on certain events, and the containing DIV adjusts accordingly. I use float:left in the container to keep it shrunk to the width of the inner divs. I use float:left in the inner divs so the layout is clean even when their contents change.
The catch is that I want the DIV container width and height to remain constant, UNLESS a particular event causes a change to the inner widths. Conceptually I want to use float on the inners for the layout benefit, but then I want to "fix" them so they don't float around. So if the container is 700px wide, I want it to remain so even if the user narrows the browser window. I'd like the container, and it's internal DIVs to just be clipped by the browser window.
I sense this can all be done nicely in CSS, I just can't quite figure out how. I'm not averse to adding another container if necessary...
Since the only desired layout changes are event-based, I am also willing to use a bit of JS. But is this necessary? (And I'm still not sure I know what to modify: container dimensions? inner floatiness? other?)
