This is a 3 column layout using Fixed side columns and a fluid center column. Each column can have a full length border and a different background colour and no images are required for this.
This layout uses my negative margins technique once again to achieve the effect of the three columns. The 2 outer wrappers supply the left and right column colours and the middle column supplies the middle column colour and is used as the main container in most respects. The left and right floats are floated out of the middle container and into the gaps at the side created by margins on the inner and middle wrappers.
