Proforms field margin not working

When using proforms and styling the proforms element, I cannot get the field margins to work.

I’m using the form inside a popup.

Any ides?

Okay, so the field margins are set to 20px by default, and overriding them by styling the class selector doesn’t work.

Unfortunately, I cannot reproduce it. There should be no default margin styles for the pro forms element. Are the styles coming from somewhere else?
