Weird blank space after footer

Site URL: https://ellipsoid-violin-xflr.squarespace.com/

Hey there guys! It seems like I might've messed up something in my CSS that resulted in a large empty space that comes after my footer. It isn't on my home page but you can see it on all the other pages, like the shopping cart. Here is my complete CSS. If anyone can help me figure out how to remove that blank space, I would appreciate it greatly! Thank you 🙂
