Thanks a lot! Worked peferct
Just one little problem is the margin-top of the h4 on this page: https://bueronerds.de/fokus/test-datenbank/
There seems to be little to none margin between the cards and the H4s. In my stylesheet, I have added this css-code for the cards:
border: 1px solid rgba(0, 0, 0, 0.125);
Do you see the problem or can you help me, to have a bigger margin between the h4 and the cards?
