The JFBCLike module has a class of "jfbclike" on it which you can use to add your own custom styles, like:
.jfbclike {margin-top: 10px; padding-left: 10px}
We're also working on improving the configuration options of a lot of the modules to make it easier to switch the looks using settings instead of having to customize things on your own in the stylesheets.
I hope that helps, but if you need anything else, just let us know.
Thanks,
Alex
