Hallo, meine Frage lautet, wie kann ich die breite und höhe der Menüleiste meiner Website ändern 
Einerseits ohne scrollen und andererseits beim scrollen? Und wie kann ich das Logo während dem Scrollen größer darstellen?
Hier meine Website: https://setup-tipps.com und unten der Code:
Habe schon einige Dinge versucht, allerdings ändert sich irgendwie nichts.
Vielen Dank für deine Hilfe:)
