css: background repeat = none?

I am looking for a way to keep a css background picture in one absolute position. When I scroll down the page I need the picture to stay in that one place. Does anybody know what attributes I would need to put in this css to make that happen? Thanks in advance.


.logo { background: url(images/logo.jpg);
background-repeat: no-repeat;
background-attachment: fixed;
position:absolute;left:10px;top:10px;
}

if it is the background image for a page then you need to assign it to the body

body {
background-attachment: fixed;
background-image: url(images/logo.jpg);
background-repeat: no-repeat;
}
