Dynamic template switcher based on user selection

I guess I replied as I did because I questioned why a user might want to switch out desktop and mobile versions. From a user standpoint they most likely don't want to have to choose. You are really best handling this with media query styles, since styles can be updated as a change occurs in the browser - namely size of the screen.

With that said, you can switch out content or styles on the fly with a little bit of jQuery then if you want the keep the state persistent, a session or cookie could take care of this.

Here's a simple example I threw together:

While I included the template in the html, it could be a separate view and loaded with ajax.

Hope this gives you some direction.
