Layout type

This positions the sidebars using absolute positioning to the left and right. Then the article uses normal flow, but has margins larger than the widths of the sidebars so that the article content is kep away from the sidebars.

As with absolute positioning generally, it becomes hard to position the footer to clear the sidebars. And some browsers tend to superimpose the content of absolutely-positioned material. I don't like using absolute positioning.
