Embed Google Form in Responsive Theme [Enigma Parallax]

Hello

I have a page on my site with a google form embedded in it.
Trouble is after the form is submitted, there is a lot of empty space where the form content was. So the user has to scroll down to the next element.
How can I make the form resize automatically to fit content, rather than a static ‘1200’ length of the embedded form? I have glanced at the google forms plugin; seems to require quite a bit of customization..

The page is https://xeniawordart.com/work

Thanks
