Landing page has a white strip at the bottom

Hi there,

This is my first time creating a Landing Page. After I tried publishing the page, it always leaves a white strip at the bottom of the page that wasn’t there when I preview. This white space is larger on certain screens which makes the whole page look unprofessional and not optimized.

Is there anyone who can help with this issue?

Here’s the link to my landing page:
