Basically what I'm trying to do is have 3 css stylesheets for desktop, mobile, and tablet. And I don't care if it is ipad or samsung galaxy tab as long as I know it is a tablet, so that I just apply tablet css to it. Same as iphone or Nexus which I don't care either. I just care about the dimension basically. That would be good if JQuery Mobile could do this. I know there is lots of code for detecting iphone, ipad, and etc, hope my post still makes sense. Thanks.
