What is a sticky footer?

Question

This question is a total noob one, but I can\'t get the difference between a normal footer and a sticky footer.

Answer 1

Taken from CSS tricks:

The purpose of a sticky footer is that it "sticks" to the bottom of the browser window. But not always, if there is enough content on the page to push the footer lower, it still does that. But if the content on the page is short, a sticky footer will still hang to the bottom of the browser window.

Here is a clear idea of what a Sticky footer is: https://css-tricks.com/couple-takes-sticky-footer/ And http://css-tricks.com/sticky-footer/
