I am a newbie and these methods are not working for me. However, I tried a margin-top property in css and simply added the value of content pixels +5.
Example: my content layout had a height of 1000px so I put a margin-top value of 1005px in the footer css which gave me a 5px border and a footer that sits delightfully at the bottom of my site.
Probably an amateur way of doing it, but EFFECTIVE!!!
