[jQuery] Firing off a jQuery action ASAP - before document ready?

[jQuery] Firing off a jQuery action ASAP - before document ready?


Hi there!
I have a jQuery action which I'd like to run as soon as possible.
Currently it runs on (document).ready but that's too late, and I see a
flicker of the page before the action takes place (importing a new
stylesheet).
Is there a way to make an action happen before the doument is ready?
Will I have to use plain javascript (noooo!), rather than jQuery?
Thanks for any light you can shed.
