I would like to change some css style in AcyMailing subscription form module but I have no success.
Documentation is for AcyMailing 5 and is not responding. I would like to pop up window for the newsletter subscription but there is no option in the module. like in version 5.
I would also like to adjust the font size, colors, etc., but I don't know in which CSS file to do this.
Maybe I searched the documentation badly, can anyone advise me?
Thank you in advance.
