Yes, I also posted this at Admin Extra, but I need as many people who know Drupal as possible to figure out how to sort this problem out. You see, my site has a drop down menu or ten at the top of the page, and it's based on the Acquia Marina theme for Drupal. However, I need to edit the background colour for only the drop down, because my images are all blue and the drop down menu is green like the default. But I can't find where the colour for that menu in particular is specified, and it shares the same classes/IDs as the left hand navigation menu, which gets ruined whenever I try to change the CSS. Is there a file for the theme I can find to add a different class to the drop down menu lists?
You'll probably have to add a background-color declaration to the primary class for the menu (ul ul li & ul li ul li). I didn't see one in the CSS style.
