html:
Code
<div id="background">
</div>
css:
Code
#background {
height: 850px;
width:928px;
background-image: url("background.jpg"):
background-repeat: no-repeat;
-moz-background-size:100% 100%;
-webkit-background-size:100% 100%;
background-size:100% 100%;
}
you can obviously change the with and height. but you need no repeat, put the image in the css, not html and make sure you have full background size.
