Can't change viewable portion of logo

[Dr Tweak]

I feel dumb for being stuck already, but here's the situation:

As you can see, only a small portion of the logo is visible. I've played around with:

includes/languages/english/RI_TEMPLATE_07/header.php

and

includes/templates/custom/css/stylesheet.css

But I can't seem to correct the problem. Suggestions?

The stylesheet will not affect the size your (background) logo file displays at, just the size of the container it goes in (unless you use fancy CSS3 styling).
You need to make the image the exact pixel size you want it to display at.

What happens if you put these 2 rules at the bottom of your stylesheet

#headerContentWrapper {
width: 540px;
}

and

#logoContent {
width: 390px;
}
