Make sure that the vertical rhythm of the site is not disturbed. Check using something like [GridFox](https://addons.mozilla.org/en-US/firefox/addon/gridfox/). Typical culprits that mess up the vertical rhythm are: - The tabs at the top of the page when logged in to Drupal - Borders around blocks (like on the [browse](http://www.christianstudylibrary.org/lib/browse) page). - The picture on the user page (when logged in). - HTML Forms - Resizing the browser window
