Hello,
1) To get transparent try to add this code into custom.css file:
.header6 .logo img{ opacity:0.8; }
2) To change the background color of the navigation use following code:
.main-nav{ background: red; }
and fixed header
.fixed-header{ background: red; }
3) Could you please clarify with more details what exactly you want to do and show us screenshots?
Regards, Robert Hall.
