Black Space Below Content

I'm using the Brine template and just created a blank page.  In the design styles I have the footer hidden.  In the body of the page I have a map and a bit of text but it's not taking up enough area on the page to  fill it and as a result, there is a black space below my white page.  It isn't there on any of my other pages, just this one.  It's almost like there's a footer there that's just a black space.  Any ideas how to get rid of the black bar?

I reached out to Squarespace and they solved it.  The solution was to go to the Design Styles and turn on the "Show Border", select the color I want, and then turn it back off.

Just here two years later to say THANK YOU! This was driving me crazy.
