I'm trying to use a sticky footer, but it seems to having a conflict with my css, I'm following this tutorial, but I want to know why the footer is in the middle of the page, what do I have to do to fix it.
My code:

The reason why you're seeing this strange behaviour with the sticky footer is because of your usage of position:absolute; on a number of your elements. Namely, the ones wrapped within the #navigation div.
Take a look at this (this JSFiddle just illustrates the problem more clearly):
I've given the offending elements all a background colour (as well as the body), so you can see that these elements are actually causing the scroll bar to extend beyond the height of the body. Absolute positioning actually takes them outside of the layout - meaning they don't cause their parent #navigation to expand, which in turn does not cause its parent .page-wrap to expand, which ultimately results in the footer not getting moved down. The footer gets put to the bottom of the body (as a result of the sticky footer CSS), which isn't quite low enough since the absolute-positioned elements extend even further below (as they are ignored by the body).
So, with that in mind, how do you fix this behaviour? Unfortunately, your sticky footer relies largely on the assumption that all content will be figured into the layout above it, or at least that the wrapper element above it will be tall enough to account for all its contents. This makes your use of absolute positioning hard to keep.
The best solution is probably to remove your current usage of absolute-positioned elements in your document, and rework how you're going to place your elements. Since I don't know what design you're actually aiming for, I can't provide an example of this. An alternative is to place an internal wrapper element inside of .page-wrap, with a min-height set such that it goes below even the lowest absolute-positioned element. However, this second method isn't too flexible, and I wouldn't recommend it.
If this isn't what you were looking for, or need more assistance in this particular matter, let me know and I'll be happy to help further. Good luck!
