Aligning CSS layer to right of screen

[envyx]

Using CSS, I'm trying to align an image to the top right corner of the screen.

Currently, I've got:

div#header {
position: absolute;
top: 0px;
right: 0px;
height: 756px;
width: 438px;
z-index: 2;
}

but this pushes the image off the screen slightly, causing a horizontal scrollbar to appear.

Is there any way to achieve such alignment, without pushing the image off the page?

Sorry, my mistake. That code works fine in IE, but in Firefox the image gets pushed offscreen some.

This very much depends on the rest of your code so a link or the complete listing is necessary.
