hello, all :) I'm having some trouble with my sideboxes. I've installed a blank sidebox, that i intend on eventually being the only sidebox (in other words, the 'information' sidebox that currently shows on my page will be disabled later)...

I'm having difficulty figuring out how to remove the bottom green border and the other gray borders from my sidebox. i've looked at several threads already, and tried about 7 different things and nothing is working. Ive looked all through "includes/templates/MYTEMPLATE/css/stylesheet.css" and sometimes i couldnt even find what CSS other threads were referencing to. is there another css file i should be editing?

i was able to remove the blank sidebox header already.

also, i would like to eliminate some of the white space below the header (above the content)... i'm guessing that came from disabling the breadcrumbs? how can i move my content up closer to the header?
