CSS sticky footer and body border-top
A common technique for adding a horizontal edge to the top of a page is to style it with something like body{border-top:10px solid #999}. Since the CSS for sticky footer already makes your body 100% in height, adding border-top of 10 pixels essentially adds 10 pixels to the height of your page 100% + 10pixels, or more than 100%. In this case, we recommend using an image to create the visual affect of a border.
