For years, the most common mobile web design practice has been to develop a unique mobile version of a website on a sub-domain. For example, if a law firm’s primary website is www.lawyersrule.com, the mobile version will live at m.lawyersrule.com. Visitors on mobile devices are automatically redirected to the “m.” sub-domain website instead of the primary website. While this approach works, it does not work as well as a newer and better trend called responsive design.
