I recently helped an NGO rebuild their website, and to some extent I relied on the built-in templates in Dreamweaver CS5. The new site replicates the NGO's original design of a logo bar at the top and a navigation bar on the left-hand side, with all of the content appearing in a div below and to the right of those elements. However, at some point--I think in the process of removing the unwanted footer and the buffer spaces at the left and right edges of the dreamweaver template--I accidentally broke the centered quality of the content div. Now the content appears adjacent to the navigation bar, aligned more to the left than in the center of the screen. It's most noticeable on higher-resolution screens.
