Having a static background image

I want the background pic to be static with the form moving over it
(as it does in Build mode), however, when published the image is tiled
and moves up with the form (see attached).

Please insert the CSS code below in order to make the background image static:

.supernova {
background-attachment: fixed !important;
}

Here's a guide on how to inject custom CSS in Form Builder V4:

1. Click the "Form Designer" button at the right.

2. Go to the "CSS" tab and paste the code in the "Inject Custom CSS" box. After that, click the "Save" button.

Hope that helps. Thank you.

Sorted out, thank you!
