When I view source csszengarden this is what I see: <div id="intro"> <div id="pageHeader"> <h1> <h2><acronym>
<div id="quickSummary">
<p class="p1"><acronym>
<p class="p2">
<div id="premable">
<h3>
<p class="p1">
<p class="p2">
<p class="p3">
<div id="supportingText">
etc etc. And it goes on.All I see are information grouped by content. The ids, and class tags describe the information. The paragraphs are ordered p1,p2,p3, because for them to make sense they have to be in that order.
Page header, quick summary and preamble are all items that belong to an introduction.
I think it's great.
