> with firefox when I resize the browser I get a flashing window on the left hand side...any
No way in Fx, I fear. It's fixed in DP.
The problem is the overflow: auto in the four white boxes.
overflow-container do jump to their origin they would have been placed
without the preceding floats spacerbox / speechbox and the relatively
positioned maincontainer. Might happen that this flicker occurs when
hovering on near links too.
Any solution would try to make these overflown boxes independent in
their localization from the prior boxes. But that means absolute
positioning of these preceding boxes and wide margins to align the white
overflown boxes correctly. That may be a way for one box, but not for
your construction, I fear.
This will cause a general re-do, but these efforts would be invested
better in a redo without these little overflown boxes, I think. More
than two scrollbars on one window are too much for me, and zooming the
text to make it readable fails because of the little width/height.
