CSS How to Make a Website Responsive Web Design and Testing Build a Three Column Layout

Question about margins.

Since margins in css collapse on themselves shouldn't the remaining screen space when we have 3 columns be 90%?

From my understanding margins should work like this:

2.5%[element 1]2.5%[element 2]2.5%[element 3]2.5% = 10%

While padding should work like this:

2.5%[element 1]2.5%+2.5%[element 2]2.5%+2.5%[element 3]2.5% = 15%

Only vertical margins experience margin collapse. Horizontal margins don't collapse at all.

This behavior was described in CSS2.1.
