making a screen move to the right while stretching the window

[Shadowing]

I'm having problems finging a tutor that explains how to do what im trying to do.

Im wanting to make a square border around my webpage then when you stretch the screen to the right. the entire box square and all its content moves to the right as you are stretching it.

 

example below

I have this div wraped around the entire page. got rid of any other css on the page

 

div.background
{
position:absolute;
width:950px;
height:690px;
background:url(images/planet2.jpg);
background-repeat:no-repeat;
border:2px solid black;
}
