I am trying to create and align three boxes with 1px solid border under the MENU. I want them to be aligned equally under as I am planning of putting images in them. Three in each row. I can create the first div box and align it, but when I try to create another one, it just overlaps the first one and I can't get it to move in-line to the next one. The dimensions are "height" 340px and "width" 260px. Because I will BE USING this format again do I create them as a div class or div ID. Please can someone explain in detail. Much appreciated.
Appreciate all the help guys. Thanks.
