I've searched for an answer, so I apologize if I missed something.
As best I can, I'm trying to re-create the our site's sidebar-navigation on its blog.* Unfortunately, I can't figure out how to adjust the margin/padding between widgets so that they're reasonably spaced.
I'm uncertain whether the relevant formatting lies in the theme's php, its css or, this widget. Help would be much appreciated.
* I've no concern about the image-rollover issue.
