I agree too ! It’s really bad actually that the confirmation message is not formated with the same color as the text color in the form. Actually the confirmation message is not visible on a dark background.
It would be great to manage some extra CSS elements for the confirmation message or for the form itself. Like it’s impossible to choose the color of the warning message (field not completed). So if my background is bordeaux, the warning text is invisible.
Changing the font or using the font of my website will be a great feature too.
It’s such a shame that you have to subscribe a PRO plan just for the unformated form.
