In The Beginning<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Page Title</title> <link rel="stylesheet" href="/path/to/jquery.mobile.css" /> <script type="text/javascript" src="/path/to/jquery.js"></script> <script> $( document ).bind("mobileinit", function() { $.extend( $.mobile, { configurationKey: configurationValue }); }); </script> <script type="text/javascript" src="/path/to/jquery.mobile.js"></script></head><body></body></html>

Think In Pages<div data-role=”page” />Only 1 visible at any timeMultiple allowed per document You can write a single-ﬁle applicationContains header, footer, and content area

<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Page Title</title> <link rel="stylesheet" href="/path/to/jquery.mobile.css" /> <script type="text/javascript" src="/path/to/jquery.js"></script> <script> $( document ).bind("mobileinit", function() { $.extend( $.mobile, {} ); }); </script> <script type="text/javascript" src="/path/to/jquery.mobile.js"></script></head><body><div data-role="page"> <div data-role="header"> <h1>Page Title</h1> </div> <div data-role="content"> <p>Page content goes here.</p> </div> <div data-role="footer"> <h4>Page Footer</h4> </div></div></body></html>

Progressive EnhancementUses the HTML5 data-* attributes to auto-enhanceand conﬁgure widgetsdata-role is now the center of your world.E.g. To create a button, add a <a href=”#” data-role=”button”>LABEL</a> and jQuery Mobile willautomagically set it up during page creation.
