The form extends beyond the footer of my page

hello, why is the form extending beyond the point it should stop?

I was also able to reproduce the issue you described on the latest version of Safari

but not on Google Chrome and Mozilla Firefox. The form page is a little extended at the bottom, but it does not exceed the footer of your website.

To fix the issue, can you please try embedding the form using its iframe embed codes? — Getting-the-Form-iFrame-Code
