How to remove the Google background (Google Forms) from the page?

Question

Google

Hello.

If you click at the bottom (under the form) the "Done" button in any Google form, then the Google Drive background will appear.
I need that when the button is ready, either the entire page reloads, or another background appears instead of the Google Drive background (white with the inscription "Thanks for your answer!"). Or there would be a form to fill out.

PHP don't offer (my hosting is special)

PS I just don't like that blue Google Drive window. And I want to get rid of it.
