The background-attachment property determines if a specified background image will scroll with the content or be fixed with regard to the canvas. For example, the following specifies a fixed background image:

BODY { background: white url(logo.gif);background-attachment: fixed }

Authors may also use the shorthand background property, which is currently better supported than the background-attachment property.
