Element for Column Browser "splitter" lines?

[WesC]

What is the element to the "splitter" lines between columns in the Column Browser?  Part of the problem is I don't know what name they go by.  I can see that some skins have them and some do not but I can't figure out what the element is.  Thanks!

for the bottom line on the horizontal layout there is "ColumnBrowser.BottomBorderLine" which uses the bdr attribute
For the vertical lines, there is no dedicated element and is retrieved from "Content[TrackDetail].Body.Default" bdr

Got it working.  Thank you so much!
