I made a web research and it seems like background-attach:fixed is relative to the viewport like position:fixed elements, so you can't make it's width or even position to fit the element. Maybe you can play with @media rules to handle certain screen sizes, but any zoom-in or zoom-out the user is doing will mess it up.
