Position absolute and margin: auto

I've got a small problem, I want my footer to stay at the bottom of the screen with position: absolute. But my margin: auto to put it in the middle of the screen isn't working anymore.

html:

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv='Content-Type' content='Type=text/html; charset=utf-8'>
        <link rel="shortcut icon" href="../IMAGES/favicon.ico">

        <link href='http://fonts.googleapis.com/css?family=Source+Sans+Pro' rel='stylesheet' type='text/css'>
        <link rel="stylesheet" href="../css/stylesheet.css">

Does margin auto work with position absolute?

New! Save questions or answers and organize your favorite content. Learn more.

What happens when you set margin to auto?

The auto Value You can set the margin property to auto to horizontally center the element within its container. The element will then take up the specified width, and the remaining space will be split equally between the left and right margins.

What does AUTO mean in margin?

So in margin: 0 auto, the top/bottom margin is 0, and the left/right margin is auto, Where auto means that the left and right margin are automatically set by the browser based on the container, to make element centered.

Why is margin 0 auto?

margin:0 auto; 0 is for top-bottom and auto for left-right. It means that left and right margin will take auto margin according to the width of the element and the width of the container. Generally if you want to put any element at center position then margin:auto works perfectly.

Since you know the width of the footer (1100px), you can just do a left:50%;margin-left:-550px to center it.

Example: Centering an absolutely positioned element
http://jsfiddle.net/vdWQG/

Therefore, footer would become:

#footer
{
    width: 1100PX;
    height: 50px;
    position: absolute;
    bottom: 0;
    left:50%;           /* Add this */
    margin-left:-550px; /* Add this (this is half of #footers width) */
    background-color: #282828;
}

If you want the element to stick on the bottom of the page as the user scrolls down, use position: fixed instead of position:absolute
