How to build a super-simple, clean CSS sticky footer

Sticky footers, although being a simple concept, have always been a pain to implement in plain CSS.

Lately I had to build one for a project here in Mikamai, and I found myself using a technique I realized not everyone knows.

It boils down to these few lines of CSS code:

    min-height: 100%
    position: relative
    margin-bottom: 50px
    width: 100%
    height: 50px
    position: absolute
    left: 0
    bottom: 0

And a basic page markup:

    Meaningful content.
        Yay, I'm sticky!

Neat, right?

You’re basically giving the body some extra “space” (via a bottom margin) in which you’ll later position your footer absolutely. So, as you can see, the¬†bottom margin on the body equals to your footer’s height.¬†

If you’re using any CSS preprocessors, you could further improve this piece of code, storing your footer height in a variable. This way, when you’ll need to edit your footer you just need to change a single value (ideally in a separated var.scss file).

Have fun!
