I am seeing something strange in both firefox and chrome when I increase
the zoom level inside these browsers, although I see nothing wrong with
my CSS... I am hoping someone on this group will be able to help.
Here is the whole story:
I have a right-floated top-level div containing three right-floated right.
The three inner divs have all box-model measurements in pixels which add
up to the width of the enclosing container. Everything looks fine when
the browser size is 100%, but when I start making the browser smaller
with CTRL+scrollwheel or CTRL+minus the rightmost margin shrinks
down too fast and eventually becomes zero, forcing my rightmost
floated inner div to fall down below the other two!
I can't make sense out of this, almost seems like some integer division
is being performed incorrectly in the browser code, but alas firefox and
chrome both display the same result.
Here is the example (just zoom out with CTRL-minus to see what I mean):

Just to narrow things down a bit, the tags of interest are the following:
div#mainContent
div#contentLeft
div#contentCenter
div#contentRight
I've searched stackoverflow for an answer and found the following

them to the problem I am experiencing:
