Remove the white spacing below the form

I also cannot remove the white spacing below the form - I tried all the solutions on your support forums for both issues, but they have not worked.

You could try this CSS:

.form-all {
    margin-bottom: 0px !important;
}

.supernova{
  background: none !important;
}

Here we remove the margin between the base of the form and the bottom of the page.

Then we remove the background of the page.
