Remove Whitespace between page content and Footer?

Good evening, I've been trying to remove the whitespace between where the page content ends, and where the footer begins.

I've tried changing Customizing > Layout > Footer - setting both sets of padding options to zero, just in case I misunderstand what they do, and it results in no changes for the footer. I'm also seeing nothing in the page content itself that would be adding the padding at the bottom either.

I guess a question related to the above is why am I seeing no changes when I dramatically change the footer widget area padding, and the footer padding. I imagine when I change some of the padding values to 1000, I should see a dramatic change to what the footer looks like, but it seems to stay identical.

Thank you
