Integrated Header with background photo on landing page

Hey there,

I’m trying to integrate my header/logo/main menu with my background photo on my landing page at https://test.leighannmarquiss.com/ (and actually am open to integrating this header row over the photos on each separate site page.)

Right now the logo and main menu are showing up as a separate row above the photo. I’ve tried finding where to make the header transparent in the theme options->colors (and only figured out how to make the space behind the main menu transparent), but even then, the BG default was grey and not a layering affect over the photo. I’m shooting for the look that is shown on the photo that appears on the demo page where I ordered the theme…. Is there a button that I click or a trick for layering the header row over the photo without touching PHP code? Or is there special coding I need to put in?

Thanks,
Leighann
