This very simple module (and plugin) allows you to switch default template style in the frontend, choosing from a list of available template styles.
It may me used for demo/testing purpose, and, also, for visually impaired people.
The user picks up default template style from a list as shown on the right side of this page, then, CG Style plugin displays all pages using this new default template style.
While testing this module, please note that my alternative template is not that beautiful, it's just there for testing purpose.....
The user choice is stored in a cookie. Its duration is set in "duration" parameter (in days). If you set it up to 0 value, cookie's duration will be current session.
Make sure you enter all the required information, indicated by an asterisk (*). HTML code is not allowed.
