screen resolution issue

[geggiot]

hi all,
i have an image footer that, with a screenresolution at 800x600 or 1024x768, it's centered with al content but at high screen resolution 1280x1024 it isn't centered.
style.css is

#footer {
background-image:url(images/footer-goingtoo.png);
background-position:center top;
background-repeat:no-repeat;
height:153px;

and grid.css is

.footer {width:1000px;}
.column {float:left;}

here can see images at 1280 and 800

You are always going to have screen resolution problems when you define things in terms of pixels. Use percent and em to define sizes.

Try
margin: 0 auto;
