data-role Attribute
<body>
<div data-role="page" id="main">
<div data-role="header">
<h1>My Header</h1>
</div>
<div data-role="content">
<p>Here is a <a href="#page2">link</a> to
another page.</p>
</div>
<div data-role="footer">
<h4>My Footer</h4>
</div>
</div>
</body>

An element that represent a jQuery Mobile widget is using HTML
attribute data-role

Immediate children of a "page" are divs with data-roles of "header",
"content", and "footer".

Page navigation
<body>
<div data-role="page" id="foo">
<div data-role="header"> <h1>First</h1> </div>
<div data-role="content"> <p>I'm first Page</p>
<p><a href="#bar">Link to second page</a></p>
</div>

<div data-role="page" id=“bar">
<div data-role="header“ data-add-back-btn="true">
<h1>Second</h1></div>
<div data-role="content"> <p>I'm second Page</p>
<p><a href="#foo">Link to first page</a></p>
</div>
</body>

 Page is basically a div identified by data-role="page" and id

 Link to page is using element a (anchor) with id name of page div as a value of href
attribute.

Back button in the header can be automatically added by adding data-add-back-btn="true“
 Another button in the header can be added using anchor tag inside header div e.g. <a
href="index.html" data-icon="check">Save</a>

Navigation bar: Navbar
<div data-role="navbar" data-iconpos="top">
<ul>
<li><a href="#" data-icon="home“
class="ui-btn-active">One</a></li>
<li><a href="#" data-icon="gear">Two</a></li>
<li><a href="#" data-icon="info">Three</a></li>
</ul>
</div>
</div>

 Navigation bar can be in header or footer
 Use ul, li and a tag
 Navigation item can be text only, icon only or both
 Standard icon without adding icon/image file can be use or use additional image/icon file.
 Default icon position is on top. Change the position of icon relative to the text using data-
iconpos attribute e.g. data-iconpos="bottom"

 To make a navigation item active use class="ui-btn-active"

Another Example: Listview
<body>
<div data-role="page" id="main">
<div data-role="header">
<h1>My Header</h1>
</div>
<div data-role="content">
<ul data-role="listview" data-inset="true" >
<li><a href="#page2#">Page Two</a></li>
<li><a href="newpage.html">New Page</a></li>
</ul>
</div>
<h4>My Footer</h4>
</div>
</div>
<body>
