Background image auto resize CSS

Perfect Full Page Background-image

Fills entire page with image, no white space

html { 

  background: url(images/bg.jpg) no-repeat center center fixed; 

  -webkit-background-size: cover;

  -moz-background-size: cover;

  -o-background-size: cover;

  background-size: cover;

}

Works in:

• Safari 3+
• IE 9+
• Opera 10+ (Opera 9.5 supported background-size but not the keywords)
• Firefox 3.6+ (Firefox 4 supports non-vendor prefixed version)
• Chrome Whatever+
