Background image is not coming when the form is embedded

Hi Team,

When we are going to add background image, it is not reflection on website, it showing success fully message but not reflection on website.

Please try injecting this CSS to your form:

.supernova {
background-image: url('https://kartrocket-mtp.s3.amazonaws.com/all-stores/image_opaxa/data/content/OPAXA-Wallpaper-1.jpg') !important;
}

Here's a guide on how to inject custom CSS to your form. 

Hope that works. If not, let us know. Thank you.
