aadmiral on "[Theme: Hueman] Footer"

Hello,

How can I attach a Footer to the bottom of the screen? Forever and regardless of the content on the page.
Currently, the footer is located right after page if the content on the page a bit - http://i.imgur.com/8cQcOtC.png

And how can I limit the width of the footer - as page size (like in boxed layout, but not using it)?

Thanks in advance
