+	<p id="closing-dialog">You can programmatically close a page styled as a dialog by navigating to another page. For example, you can use the <code>pagecontainer</code> <a href="/pagecontainer/#method-change"><code>change</code></a> method:
+<pre><code><![CDATA[
+$( ":mobile-pagecontainer" ).pagecontainer( "change", "somepage.html" );
+]]></code></pre></p>
+
+	<p>You can also simply go back:
+<pre><code><![CDATA[
+$.mobile.back();
+]]></code></pre></p>
