It's the copyright p margin in the footer.
p.copyright { margin-bottom: 0; }
Вопрос
I've tried using chrome's developer tools to isolate the problem but can find the culprit there is a margin or padding at the bottom of this page I'm developing. It looks like a margin on the body or the footer but I just can't seem to find it. Looking for a fresh pair of eyes.

The margin-bottom on your copyright class seems to be the culprit. If I set it to zero then the white space at the bottom goes away.
