Footer Partly Invisible

Hey folks,

I’ve got a problem with my footer. I would like it to stick to the very bottom of my pages. But when I try to move it there the bottom part of my footer gets cut of and becomes invisible…

I’ve looked everywhere in the html and Css for what could be causing this, but haven’t found it.

I’ve tried everything I can think of… So any ideas? 🙂
