Div's with different heights, align them side by side at the top

Question

I want to align divs side by side, but the heights are not equal, which causes that there is a blank space between div's the first line with lower height and the div's in the second row.

I want this:

and not this:

Answer 1

I would use 3 divs (lets call them A B and C) as columns

These would have style="float:left;width:32%;" * note width CAN be less than 32% and can be set in px

A would contain 1 and 4 while B would contain 2 and 5. Finally C would contain 3 and 6.

There is absolutely no need for plugins and it can (and is currently, by me) being done with css alone.
