XF 2.0 Where can I find the XF variables, to modify them?

[vexx]

My problem is pretty simple (I think), I'm trying to customize a theme but I get different XF variables for different settings. I have no idea what are the values for those variables and how can I edit them.

ex: @xf-borderRadiusSmall navigationBarHeight @xf-responsiveWide etc

Where can I find these to customize them?

Those are style properties. You edit them in the ACP.

I figured that, problem is, I cannot find them in Style Prop in ACP. I'll look again maybe I'm missing something

If you search for the part after @xf-, you'll find them:
