If you only had to worry about Firefox and Webkit browsers, what CSS would you use to make the footer in the following HTML not rise above the bottom or the screen (and go lower
* { display:block; }
You are going to have to change the display to inline in your wrapper after that though.
Working and tested on:
Google Chrome
Safari
Opera
Internet Explorer
Firefox
EDITED CODE (added overflow:auto; to #aside and #Article to fix the overflow)
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
html,body{height:100%;width:100%;margin:0;padding:0;background-color:red;}
#Header,#Article,#Aside,#Footer{position:absolute;}
#Header{top:0;left:0;width:100%;height:60px;background-color:blue;}
#Article,#Aside{top:60px;overflow:auto;bottom:30px;}
#Article{left:0;width:70%;background-color:green;}
#Aside{right:0;width:30%;background-color:yellow;}
#Footer{bottom:0;left:0;width:100%;height:30px;background-color:pink;}
</style>
</head>
<body>
<div id="Header">Header</div>
<div id="Article">Article</div>
<div id="Aside">Aside</div>
<div id="Footer">Footer</div>
</body>
</html>
PS: Background colors are illustrative, thus the css can me more compact by avoiding repeated attributes!
Another answer for those who only need to target the latest versions of browsers utilizing flexbox and viewport units.
