DIV Positioning Problem with client's site
I have a new page located at http://www.mazzis.com/indexnew.php
with the CSS file at http://www.mazzis.com/styles-new.css . In Mozilla, Firebird and IE, the navigation over on the right has a black line at the bottom as well as all of the separating lines flowing into the main content area. I've tried adjusting the CSS, but I can't seem to figure out where I'm going wrong and allowing the lines to flow over. I want them to butt up against the edge of the content box perfectly. Any suggestions would be greatly appreciated. Thanks!
