This works, but what do the two parameters for do (margin: 0 200px;) and is it possible to use percentages instead of absolute and relative.

Margin is to align the DIV's in proper spacing with each other.
also percentage can be replaced by pixels but not by position.

Thanks, I am wondering about the two parameter for margin (0 and 200px) is one left and the other right.  is it also possible to use   (width = 20% for left column, width=60% for midle column, and width = 20% for the right column.
