Can't get rid of white borders

[Disting]

Hello!
I'm not sure if this is the right forum to post this in, but while I was styling my forum, something unexpected happened.
I got a white line under every forum header and thread row.
You can see what I mean here: http://www.nextgenhardsurface.com/forum.php
And here (more noticable): http://www.nextgenhardsurface.com/forumdisplay.php?15-WIP-Work-In-Progress

This occured when I made the (I think) body bg transparent.

I'm not an experienced VB skinner, so I'm sorry for not being able to explain my problem better.

Looking forward to hearing from you!

Cheers! :)

It's from this:
.forumhead + .childforum .L2:first-child .forumrow, .forumhead + .L2 .forumrow { border-top: 1px solid;}

It's from this:
.forumhead + .childforum .L2:first-child .forumrow, .forumhead + .L2 .forumrow { border-top: 1px solid;}

Yeah, I found that as well, but I can't find it in the stylevars, or the templates.
I could really use a hand with that.

Cheers!

Ok, I managed to remove it in the forum tables now, but not in the thread tables. ( http://www.nextgenhardsurface.com/forumdisplay.php?15-WIP-Work-In-Progress )

Any idea where I could find that?

Cheers!

I would strongly suggest you get firebug for firefox to figure this sort of thing out.

The borders on that page are from:

.threadbit .sticky { background: none repeat-x scroll left bottom #3E3E3E; border-color: -moz-use-text-color #C4C4C4 #C4C4C4; border-right: 0 solid #C4C4C4; border-style: solid; border-width: 1px 0 0;
....}

.threadbit .nonsticky, .threadbit .deleted, .threadbit .discussionrow, .threadbit .ignored { border-color: -moz-use-text-color #C4C4C4 #C4C4C4; border-right: 0 solid #C4C4C4; border-style: solid; border-width: 1px 0 0
.... }
