Wordpress change theme button

Hi all,

Apologies if this has been asked before, I’ve searched the forums but could not find an answer.

I’m new to Wordpress/PHP and have been asked if it is possible for the user to be able to change the theme of the site with a button/select box? So create two or more stylesheets which would change background/link colour etc. then the user can choose to see the blue site or red site etc.


Never mind. Found it now.
