Automatically resize images with browser size using CSS

I want all (or just some) of my images getting resized automatically when I resize my browser window. I've found the following code - it doesn't do anything though.

HTML

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
        <link rel="stylesheet" href="style.css" type="text/css" media="screen" />
    </head>
    <body>
        <div id="icons">
            <div id="contact">
                <img src="img/icon_contact.png" alt="" />
            </div>
            <img src="img/icon_links.png" alt="" />
        </div>
    </body>
</html>

CSS

body {
    font-family: Arial;
    font-size: 11px;
    color: #ffffff;
    background: #202020 url(../../img/body_back.jpg) no-repeat top center fixed;
    background-size: cover;
}

#icons {
    position: absolute;
    bottom: 22%;
    right: 8%;
    width: 400px;
    height: 80px;
    z-index: 8;
    transform: rotate(-57deg); 
    -ms-transform: rotate(-57deg); 
    -webkit-transform: rotate(-57deg); 
    -moz-transform: rotate(-57deg);
}

#contact { 
    float: left; 
    cursor: pointer; 
}


img { 
    max-width: 100%; 
    height: auto; 
}

How can I basically have a fullscreen design (with background-size: cover) and have div elements be at exactly the same position (% wise) when resizing the browser window, with their size also resizing (like cover is doing for the background)?

To make the images flexible, simply add max-width:100% and height:auto. Image max-width:100% and height:auto works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to add width:auto9 for IE8.

source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries

for example :

img {
    max-width: 100%;
    height: auto;
    width: auto9; /* ie8 */
}

and then any images you add simply using the img tag will be flexible

JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).
