Section heights suddenly changed!

I was editing my site, when all of a suddenly all the section heights changed. Every section has additional spacing added far beyond what I initially designed, and adjusting the section heights/styles doesn't do anything.

Context: I was adding a code injection when it happened, but removed what I added, and it didn't go back to normal - so I am unsure on the cause! Help!

Attached is an example of the footer MASSIVE, and what it's supposed to look like.

Thanks @creedon - I found 2 instances of that code that were supposed to be isolated something else, but weren't. Not sure why it suddenly changed on me, but alas I've found a workaround. Thanks again!
