    If you are referring to the page background image of the only form in your account, I suggest you add the following CSS codes below to your form. To learn how to do that, please see this guide: How-to-Inject-Custom-CSS-Codes

    .supernova {

        background-size: 100% 100% !important;


    I hope this helps. If you have any further questions or concerns, please feel free to contact us again anytime.

    Thank you.
