Abstract:

With old-school table layout methods, vertical positioning is a piece of cake. With CSS layout, it's a piece of something else. New ALA contributing writer Bobby van der Sluis shows how to regain control of footers and other vertically positioned layout elements via CSS, JavaScript, and the DOM.
