[vB4] Where is this and how to remove?

[Off_Topic]

Whilst modifying a vBulletin 4 theme we've come to a stop. This white line, border or margin... whatever is causing it, is from the default vBulletin 4 theme. Looking over stylevars and CSS I am stumped. It's in forum display between threads.

Highlighted in red, what is it and how do I remove/modify it.

Cheers.

Get firebug, and add-on for firefox, and it will making finding these things easy. It's in here:

.threadbit .nonsticky, .threadbit .deleted, .threadbit .discussionrow, .threadbit .ignored {
border-color:#FFFFFF #C4C4C4 #C4C4C4;
border-style:solid;
border-width:1px;
....

}

Find that class and change it or add your own css to change it.
