I edited the page background image of my form and now its wraping the image when scrolling

Before I added a different image, only the form would scroll.  Now the whole page scrolls and the image is repeated.  I went to the advanced designed and it is not set to repeat.  When I try to edit it there it loses all my other settings.  Help.  My form is https://form.jotform.com/visitationpto/avenues-bistro 

Hi, 

I have created a little style code (css) for your form.

I hope now it looks as you described.

Thanks for using JotForm.

Regards.
