If I have a form with transparent Wallpaper, it appear great on my website by using my default background. However, using Zoho Forms SAVE button, the user is directed to Zoho Forms managed page and a blank background.

Alternatively, I can include a Wallpaper image on the Zoho Form, but that image is then shown on my website when embedded. (I use a fixed height when embedding)

I would like to know if there is a way to assign a background image for the form (perfect for saved form) but force a transparent background when embedding into my website using JavaScript or iframe?
