Anchor in about page not visible

[KlausIllmayer]

At which URL did you encounter the problem?

https://vocabs.acdh.oeaw.ac.at/en/about#editor

What steps will reproduce the problem?

1. Click on the link
2. You won't see the header "Vocabs editor" where the link is pointing to
3. This is because the navigation bar seems to be ignored and the header is behind the navigation bar block

What is the expected output? What do you see instead?

I expect that I see directly down below the navigation bar the header "Vocabs editor" and not jump somewhere into the text about the vocabs editor, which is very irritating.

What browser did you use? (eg. Firefox, Chrome, Safari, Internet explorer)

Firefox on a PC, didn't test it in mobile version
