can i make an image 100% of back ground in css

[autopost]

I have this back ground image that is fixed but it only spans about 86% of a certain papge is there a way i can make to auto adjust to browser resolution and still stay fixed? but the user would be able to scroll?Try this



<SCRIPT language=JavaScript1.2>
<!--
function init(){
img_width = (document.layers) ? window.innerWidth : document.body.clientWidth;
img_height = (document.layers) ? window.innerHeight : document.body.clientHeight;
bg_img.width = img_width
bg_img.height = img_height
}
onresize=init

// add onload="init()" to the opening BODY tag

//-->
</SCRIPT>

<img name="bg_img" src=http://www.webdeveloper.com/forum/archive/index.php/"pic1.jpg" border=0 style="position:absolute;left:0;top:0;z-index:-1">
