CSS for checkout page EXCLUDING order received page

Hi,
I need to target certain selectors on my site but I need to exclude the selectors that are on the checkout page. I know I can do this with

body:not(.page-id-xyz) .myselector{}

where xyz is the page id of the checkout page. But I still need the css to be applied for the selectors on the order received page, which is just an endpoint of the checkout page. So if I was to use the above css, it would also exclude the myselectors on the order-received page, which I want included. is there a selecor specifically just for the checkout page that does not include the order-received page?
