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. Fixes #161

<p>The <code>.offset()</code> method allows us to retrieve the current position of an element <em>relative to the document</em>. Contrast this with <code>.position()</code>, which retrieves the current position <em>relative to the offset parent</em>. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), <code>.offset()</code> is the more useful.</p>
|
|
<p><code>.offset()</code> returns an object containing the properties <code>top</code> and <code>left</code>.</p>
