Centering a background image, using CSS

Question

I want to center a background image. There is no div used, this is the CSS style:

body{
    background-position:center;
    background-image:url(../images/im         


        

Answer 1

I think this is what is wanted:

body
{
    background-image:url('smiley.gif');
    background-repeat:no-repeat;
    background-attachment:fixed;
    background-position:center;
}
