This question is a total noob one, but I can\'t get the difference between a normal footer and a sticky footer.
This CSS sticky footer code pushes a website's footer to the bottom of a browser window. It is valid CSS and HTML with no unsavory hacks, so it works in all of the major browsers (even the now defunct IE5 and IE6).
How to use the CSS Sticky Footer on your website,
Add the following lines of CSS to your stylesheet. The negative value for the margin in .wrapper is the same number as the height of .footer and .push. The negative margin should always equal to the full height of the footer (including any padding or borders you may add). Follow this HTML structure. No content can be outside of the .wrapper and .footer div tags unless it is absolutely positioned with CSS. There should also be no content inside the .push div as it is a hidden element that "pushes" down the footer so it doesn't overlap anything.
I would guess a sticky footer is one that stays fixed to the bottom of a page, regardless of the length of content. Like this.
