Hi there,
This issue has been mentioned before. But unlike the other users, I’m not using a cache plugin and still can’t understand where the CSS line-height property derives from.
My modal looks like this in the backend (convert plus) 
But looks like this in the browser: 
I tried to add an overwriting CSS attribute with line-height using !important but it didn’t work out. Where does this line-height come from?
It’s on the index page of www.dezernatzukunft.org
Thanks for your help.
