.htacces subdomain to file

Hi /prog/,
I have a problem making a subdomain that points to a file, I know how to make it with folders, like lol.domain.org will be pointing to domain.org/lol but is it possible to make .htaccess point lol.domain.org to domain.org/index.php?page=lol ?
I promise i've tried multiple time but failed.

Try using fucking ABSOLUTE URLs FOR THE CSS, THEN.

Fucking idiot. Please post the link of your website when you're done.
