<p>The <code>.before()</code> and <code><a href="/insertBefore">.insertBefore()</a></code> methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target. With<code> .before()</code>, the selector expression preceding the method is the container before which the content is inserted. With <code>.insertBefore()</code>, on the other hand, the content precedes the method, either as a selector expression or as markup created on the fly, and it is inserted before the target container.</p>
<p>Consider the following HTML:</p>
<pre>&lt;div class="container"&gt;
  &lt;h2&gt;Greetings&lt;/h2&gt;
  &lt;div class="inner"&gt;Hello&lt;/div&gt;
  &lt;div class="inner"&gt;Goodbye&lt;/div&gt;
&lt;/div&gt;</pre>
<p>We can create content and insert it before several elements at once:</p>
<pre>$('.inner').before('&lt;p&gt;Test&lt;/p&gt;');</pre>
<p>Each inner <code>&lt;div&gt;</code> element gets this new content:</p>
<pre>&lt;div class="container"&gt;
  &lt;h2&gt;Greetings&lt;/h2&gt;
  &lt;p&gt;Test&lt;/p&gt;
  &lt;div class="inner"&gt;Hello&lt;/div&gt;
  &lt;p&gt;Test&lt;/p&gt;
  &lt;div class="inner"&gt;Goodbye&lt;/div&gt;
&lt;/div&gt;</pre>
<p>We can also select an element on the page and insert it before another:</p>
<pre>$('.container').before($('h2'));</pre>
<p>If an element selected this way is inserted elsewhere, it will be moved before the target (not cloned):</p>
<pre>&lt;h2&gt;Greetings&lt;/h2&gt;
&lt;div class="container"&gt;
  &lt;div class="inner"&gt;Hello&lt;/div&gt;
  &lt;div class="inner"&gt;Goodbye&lt;/div&gt;
&lt;/div&gt;</pre>
<p>If there is more than one target element, however, cloned copies of the inserted element will be created for each target after the first.</p>
<p>In jQuery 1.4, <code>.before()</code> and <code>.after()</code> will also work on disconnected DOM nodes:</p>
<pre>$("&lt;div/&gt;").before("&lt;p&gt;&lt;/p&gt;");</pre>
<p>The result is a jQuery set that contains a paragraph and a div (in that order).</p>

Big update: In starting markup, pages should now be identified with the attribute data-role="page". This allows us to then add ui-page programatically, hiding all non-active pages, and apply ui-page-active to one page at a time to show it. mobile.js is updated to find pages by this attribute now, instead of ui-page class. fixes issue 32 2010-09-18 16:20:35 +00:00			`<div data-role="page">`
updated markup to use data-role attrs in place of classes for header/content/footer 2010-09-21 14:58:54 +00:00			`<div data-role="header">`

switched up padding and margins on content div. Now it will get 15px padding, unless its a fullscreen page. Inset listviews have no margin now, and regular listviews have -15px margins. Also, collapsibles now have no padding. Updated HTML to remove ui-body classes for content divs, to match these changes.
