Background Attachment

Syntax:	background-attachment: <value>
Possible Values:	scroll \| fixed
Initial Value:	scroll
Applies to:	All elements
Inherited:	No

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(candybar.gif);
       background-attachment: fixed }

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