Sometimes for a short-content page the footer climbs up and leaves a blank space at the bottom of the page. This looks ugly when content becomes small in height. But, as the name depicts itself, footer should be at the foot/bottom of the page. This post will help you tune the page and css to make the footer stick to the bottom regardless of content height. Not to mention, the footer will go down like normal when content exceeds the view-port height. The solution is to force the footer down to the bottom of the page for smaller contents.
