Successful install, but not displaying correctly

[hcgriggs]

I've forked and cloned the theme into my [theme]/neatline/exhibit/theme/[neatline-theme-test]. While the exhibit has changed, it is not displaying within the parameters of the exhibit. Instead it extends off the page, and does not let me scroll, either. I've included a screen shot of the issue since I'm hosting the site locally. Is this a CSS fix? Or did I install something incorrectly?
