I am working with a responsive joomla theme. For the most part it is good, but I have a couple pages that are annoying me. Because of the type of content on the pages they will not work well when in responsive mode for mobile devices so I need to deliver differing design concepts to normal desktop vs mobile visitors.
To accommodate this need the theme shop has provided a couple css classes to allow you to hide content from desktop vs mobile and vice-versa. Although the content is hidden, it still exists in the page so in theory although the mobile-friendly content does not display to desktop visitors it lives symbiotically. In my view of the world not only might this slow down the page, but it feels like duplicate content, perhaps even sublime keyword-stuffing.
Your IMHO much appreciated.
