custom $navclass classes

[waza]

Hey,
In my usercp_shell template I want to add some extra buttons.
But where can i add new navclass classes for the buttons.
As example there is:

PHP Code:

<td class="$navclass[profile]" nowrap="nowrap">link</td> 

If i duplicate this and i click on 1 of the links than bot buttons are marked as clicked on.

If I just give it a name then it doesn't have a color.

So where can I add those css things.

Btw, I took a look at the main css things in my template in the admincp but didn't find it...
