Kubrick header

in your stylesheet.css file, there should be a section like

#nav {background, text, image properties in here}
#nav.a {link properties}
etc...

in there, there should be something to identify what color that bar should be. without seeing the code itself, i can’t do much else..

here is the image to edit or replace
