[wp-hackers] Selective CSS based on Shortcode?

[Matthew Kettlewell]

I'm wanting to override CSS in posts that use a shortcode from my
plugin....

problem is that I'm not sure how to go about doing this...

I'm using add_shortcode() to check in the post contents for the shortcode,
but I'm needing to know if the shortcode is used when I'in in header.php.

I've tried setting meta_data in my function that is called from
add_shortcode(), but it's too late...

Is there a way to get the shortcode value before header.php is called?

Thanks
Matt
