Your image is only 1152px wide, so if anyone views your site on a browser that is wider than 1152px they’ll see whatever the background of your header is. The .head-wrap is what wraps around your header, and since you’re using the black color scheme it is set to show black. Line 2749 –
.epik-black .head-wrap,
.epik-black .welcome,
.epik-black .home-feature-bg-dark,
.epik-black .author-box,
.epik-black .footer-widgets {
background: none repeat scroll 0 0 #111;
}
So the only way to have the entire background of your header to be an image or color is to make edits to the .head-wrap
You could change the min-height on line 1962 in your css like this if you wanted –
.header-image .site-title a {
float: left;
min-height: 154px;
width: 100%;
}
and that would decrease a little bit of the space directly under the header (right above the nav). The nav section is black and each nav link has it’s own padding.
Hope this helps.
