CSS - Is THIS Possible?

[Roy Schestowitz <newsgroups@schestowitz.com>]

In my CSS I included the following:


#Div_png_top {
        font-size: 40px;
        text-align: center;
        position:fixed;
        top:10px;
        right: 300px;
        background:url(/IMG/blog_css/up.png) no-repeat top left;
        width:50px;
        height:50px;
}


My question is: can the line

right: 300px;

be replaced so that the object always appears in the _center_? I tried many
things to no avail.

Thanks in advance,
Roy
