I am making a new layout and I need to make a section for 4 columns with equal padding between them. I have messed with relative and absolute positioning, floating left with margins to make the white space. My problem is that I need no margin on the first and last column and I am finding first-child and last-child to be problems. I also want to optimize this layout for wordpress so I am trying desperately hard not to assign classes to individual columns that way I can make my loop in wordpress and not have to worry about it. What do you think?
