7.0 creating a fixed header which shrinks while scrolling

Site URL: https://www.sup-event.com/

Hey,

I would like to fix the header, but make it shrink and let the logo vanish when you scroll down.

Can you suggest some CSS Coding? I tried to look for answer here in the forum but I couldn't find anything that would work.

Thank you an nice greetings
