XF 2.2 Change font i

[jansen]

How can i change the font?

I've read it all through but I still don't understand.

What do i have to write in the Typography. And how can i change the font in the navigation bar like here: https://prnt.sc/vks5oh

This is the fontface but idk what to do with it:
@font-face { font-family: 'GeForce Light'; src: url('GeForce-Light-Alt.eot'); src: url('GeForce-Light-Alt.eot?#iefix') format('embedded-opentype'), url('GeForce-Light-Alt.woff') format('woff'), url('GeForce-Light-Alt.ttf') format('truetype'); font-weight: normal; font-style: normal; }
