Hello Michael,
thanks for your suggestion, but that’s still not the solution… The issue is that the fields should displayed side-by-side in the desktop view, but as soon as the resolution gets too low, the fields should be displayed one below the other. As far as I know, this only works with a DIV tag and CSS. If you know a HTML solution for this, that would be great, because a snippet like that is always useful…
… it would also super to have a function “additional CSS” in thenewsletterplugin.
