How do I change the Interface Font without affecting other applications in Zorin OS Lite?

The tip I gave above in regards to using a custom .css may give you the fine-point control over the UI of most apps... I can probably help you I.D. the classes you need to specify if you clearly define what Interface elements you wish to change.

Ok, I can do that. I think that would be better. But I will be busy for a few weeks. I am not marking this thread as solved because I would like to continue the discussion on creating/modifying a custom .css file when I will be free.
I will not be posting for these few weeks, unless I run into a trouble.

That is sad news, but will look forward to your return.

I was able to modify the gtk.css file myself. I managed to change the font of the panel and Thunar file manager and the font of the window titlebars. Thank you very much for pointing at the right direction.
