A Simple Three-Column Layout

Step 2 - the three divs are now aligned vertically. The navigation div (with its right border in red so you can see where it is) has been absolutely positioned so it is removed from the flow of the document. The right column (with its left border in red so you can see where it is) has also been absolutely positioned and its right property is set to zero.

Next, we will set the margins on the content area so it no longer overlays the side columns.

This is the right column positioned in the top right of the browser.
