I am having an issue with the Structure Theme. I want to customize the colors to suit my site, so I changed the main body background (not page background) color in the stylesheet:
margin: 0 auto;
padding: 0 12px;
I also changed the main navigation background color:
The only coding I changed was the actual colors- nothing else. The problem is, once these 12 numbers/letters were changed, the background of the navigation menu does not show in Internet Explorer. It's fine in Firefox.
