behaviour: Describe the issue
device & browser: Chrome and Safari
Comment/Question: *I think the grid is fine like that but I would just confirm with meinBerlin people if that's allowed according to the StyleGuide cause I thought every form should be full width, but maybe that's fine.

Another thing I saw was the Spacing between lines that is different than the style guide(24)
Currently its 19.2
