Gray area appears at the bottom of the form instead of my background.

Hi, i upgradet from free to bronze.

but instead your branding, on a smartphone there is white area visible. there should be my background image.

on a pc it looks beautiful. not on the phone.

I am not able to replicate the issue. This is how I see the form at my end, see the image below:

Could you please try again and see if you are still facing the issue?

This thread is Public, so you should be able to view it. 

I tested your form using Samsung Galaxy S5 emulator and I was able to replicate the issue. 

To resolve the issue add this CSS code to your form:

.supernova {

        background-repeat: no-repeat;

        background-attachment: fixed;

    }

@media screen and (max-width: 480px){

    .supernova {

        background-image : url("https://www.jotform.com/uploads/neobeluga/form_files/Hintergrund1.5ca30219744055.15953064.jpg");

        background-size : cover;

        height : 100%;

        overflow: hidden;

    }

    body {

        height : 100%;

        overflow: scroll;

        -webkit-overflow-scrolling : touch;

    }

}

How to Inject Custom CSS Codes

Here is a demo form - https://form.jotform.com/90914215442957

Feel free to test it and clone it. 

Could you please let us know which phone are you using so that we could check and guide you further.

On testing, I could not replicate in the Samsung Chrome browser. Here is the screenshot for the same:

Looking forward to your response.

Thanks.

if you scroll down at chromebrowser then the address bar disappears at the top and at the bottom the gray area comes for it
