Main Header Image

Hello,

I’m trying to add an image to my main header. I want the image to display and to turn off the logo in the header completely as it is included in the image. The image dimension are 1140 x 300, so I would like the header to be 300 px tall. I have the site set to boxed width at 1140 px.

This is the CSS I’ve added to get to the point I’m at, but I can’t figure out how to get the image to fit in the width of the content box and make the header tall enough to see the whole image.

I also tried removing the logo from the Logo Settings but now it just gives me a line of text. I’d like to have nothing visible in the header about the main nav except the background image.
