any idea which of the multiple CSS files would need this line?

man......in my opinion, dnn would be a great product if not for this one issue. i have dug through directories, online tutorials on the hierarchy of stylesheets etc....but i can NOT affect vertical alignment of modules within a pane. i just installed an image rotator module and it works great. BUT......there is a good inch and a quarter above and below the module....with no apparant way to tighten it up so....it looks like crap. people say "well don't use the default skin whatever you do" - why would the default be so difficult to work with?

so let's say you are me.....and you just added an image rotator module and it has over an inch of blank space above it and below it......what would you do to reduce that?
