An interesting technique, and something I  will definitely file for  
future reference, but not really appropriate for the CSS example I  
gave.  Is it really the *best* way to have to have a bunch of GET  
string attached to every page of a site just to customize some CSS???   
Talk about ugly URLS for such a minor thing.

I think the best is to simply output the custom CSS to wp-head.

Question:  Do enqueued CSS or scripts come specifically before or  
after wp-head output?  Is it ***definitive*** or does it depend on the  


P.S. -- In all of this, I'm not sure I've ever heard a satisfactory  
explanation for WHY all these things should be enqueued anyway.   
Dependencies, sure, but why for a stylesheet or script that doesn't  
have any dependencies?
