At
bluerobot they have a
cool 3 column layout design in CSS (stealing it is allowed). I tried to tweak it a bit to make it fluid and the results are
here.
However the left and right elements keep overflowing into each other by exactly 10 pixels, no matter what size the window is.
Examples are
here and
here.
Why is this overflow happening and what do I do to prevent it.
Also, is it possible to say in CSS
margin-left: 40%-16px or anything like that. Can you mix and match units as well as do basic arithmetic?
