Different wording, same concept.

But that is not how this should be done.

And annoy your visitors to no end :->

The proper way is to tell visitors with mobile devices that a mobile-
optimized version is available for them unless they have switched from the 
mobile-optimized version to the desktop-optimized version (which is possible 
e.g. in Mobile Chrome by simply checking a checkbox in the menu).

As an alternative, media queries can be used so that the stylesheet is 
adapted to the mobile device and no mobile-optimized version is necessary.
