How do I make a background in a pet profile not repeat itself? To stay still while everything else scrolls?

I've tried background-repeat:no-repeat; but that doesn't work. There seems to be no other code for it to work that I can find :(

Thanks for any help

background-repeat: no-repeat; should stop it repeating, but for it to stay still while everything else scrolls, you need to use background-attachment: fixed;

:)

THANK you so very much!!!

You're welcome! :D
