thanks for you help. This changes the spacing. This was the “subtle” part of the problem.
The “real” problem occures in Firefox (Edge and Internetexplorer work fine). For the first links (Über uns / Leistungen) it’s ok but if you want to jump back from an inner menue to e.g. “Produktionen” or “Kunden” you are always landing on “Aktuell”.
Can you reproduce this?
Thanks and regards!
