White Strip At Bottom Of Page

At the bottom of my page there is a white strip between my last content box and the copyright footer.

This happens a lot, so I’m hoping you can help me fix this.

Is there a way to get rid of that empty section using *the drag and drop builder*? I can fill spaces when there is a section below it, because I can put a -20px in the top margin. But when the footer is the *last box* I don’t have any control over the top margin.

The visual editor doesn’t load, so I can’t use that.

Thank you for your time!
