Tripane Skin-remove or make Tab flush with body? [UNFIXED]

[M33R4]

I'm using a Tripane skin in my Project.
I only need the Contents to show in the left-hand pane.
I've therefore unticked Glossary, Index, etc to stop them displaying and now only Contents is displaying in a single tab - as per attachment.

Issue: I am not keen on the gap between the Contents tab and the body pane. Is there any way I can solve this issue please

What I would have liked is the look of the MadCap Help site: https://help.madcapsoftware.com/flare20 ... arted.htm. Here you can see clean lines between the Content on the left and the body on the right. That is an ideal layout for me.

My output is both HTML5 and Print (PDF and Word)

Many thanks

Cannot be resolved: the tabs are in the SKIN and this is all hard-coded. I therefore could not resolve the issue from SKIN editor or stylesheet. Perhaps someone knows some Java to resolve this? Personally I was not able to so I just changed to another skin navigation instead.
