Joomla! Template 002041 - Item Support

I installed the extensions and the commercial package, works so far.

How do I get the design/sub-template/css of the "Item" page.

see http://www.asdesigning.com/demo/asj41/index.php/services/dining-room/dining-room-1

(e.g. layout and design of the the extra attributes / "Specification")

I used manual installation. After using the quickstart installation, I found out, that "Specification" are no Extra Fields but just HTML tagged descriptions with CSS additions.
It would be better to have that as Extra Fields. I achieved the same layout by adding/modifing the following line in k2.css:

div.itemExtraFields
{ overflow: hidden; width: 100%; padding: 20px 0 0; }

div.itemExtraFields h3
{ font-weight: bold !important; padding: 0px 0px 10px; font-size: 14px; border-bottom: 1px solid #D4D4D4; }

.itemExtraFields ul li
{ background: none repeat scroll 0 0 #EEEEEE; margin: 5px auto !important; min-height: 25px; padding: 0 15px !important; border: 1px solid #ccc; background-image: none; }

div.itemExtraFields ul
{ margin:0; padding: 10px 0px 0px 0px; list-style:none; }

div.itemExtraFields ul li.even
{ float: left; width: 43%; overflow: hidden; }

div.itemExtraFields ul li.odd
{ float: right; width: 43%; overflow: hidden; }

div.itemExtraFields ul li span.itemExtraFieldsLabel
{ float: left; padding-top: 3px; width: 40%; }

div.itemExtraFields ul li span.itemExtraFieldsValue
{ float: left; padding-top: 3px; width: 60%; }
