A jQuery Mobile webpage must start with an HTML5 doctype to take full advantage of all of the framework's features. In the head section of a webpage, references to jQuery, jQuery Mobile and the mobile theme CSS are also all required. jQuery Mobile has guidelines on the structure of pages themselves. In general, a page structure should have the following sections:

Page
This is the page displayed in the browser. The attribute data-role="page" is used to specify a page which can contains header, content and footer.
Header
This creates a toolbar at the top of the page. The attribute data-role="header" is used to specify a page's header. Typically, it contains the page title or search button or back button.
Content
The attribute data-role="content" is used to specify a page's content. This contains the content for your page, like text, images, forms and buttons, etc.
Footer
The attribute data-role="footer" is used to specify a page's footer. This creates a toolbar at the bottom of the page. Typically, it contains navigation links, copyright information or whatever you need to add to the footer.

Structure of a jQuery Mobile Page

<!DOCTYPE html>
<html>
<head>
 <title>jQuery Mobile</title>
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css" />
 <script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
 <script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
</head>

<body>
 <div data-role="page">

 <div data-role="header">
 <h1>Header Text</h1>
 </div>

 <div data-role="content">
 <p>jQuery Mobile framework introduction!!</p>
 </div>

 <div data-role="footer">
 <h1>Footer Text</h1>
 </div>

 </div>
</body>
</html>

All of the above containers can have any HTML elements like paragraphs, images, headings, lists, etc.

Using Page as Dialog

A dialog box is used to show information or take input from users. You can also open a page within dialog box by using data-rel="dialog" attribute to the link as given below:

<div data-role="page" id="page1">
 <div data-role="header">
 <h1>Header text</h1>
 </div>
 <div data-role="content">
 <h1>Welcome to Page1!</h1>
 <a href="#page2" data-rel="dialog">Go to Next Page</a>
 </div>
 <div data-role="footer">
 <h1>Footer Text</h1>
 </div>
</div>

<div data-role="page" id="page2">
 <div data-role="header">
 <h1>Dialog Box</h1>
 </div>
 <div data-role="content">
 <h1>Welcome to Page2!</h1>
 <a href="#page1">Go to Previous Page</a>
 </div>
 <div data-role="footer">
 <h1>Footer Text</h1>
 </div>
</div>

When you will click on link Go to Next Page, page2 will be open in the dialog box as shown below:
