The default outline template got a couple of updates.
The slogan at the bottom is now hidden. It's still there, and if you want to bring it back, add this bit of CSS in a #style directive: .spSlogan {display: inline;}
You can now put a background image on an outline page. Add a backgroundImage attribute to the title headline. Its value is the URL of an image. It should be pretty big. This page uses the outline template and has an image.
I updated the GitHub repository with the latest versions.
If you haven't checked it out yet, it's really sweet.
Basically you can add CSS styles at any level -- in your cmsPrefs.opml file, or on an individual page. It's one of the coolest new CMS features in Fargo 2.
