title: Is it OK to skip heading levels
body: <p>I've always frowned upon skipping heading levels in HTML documents, especially for reasons of screenreader accessibility. Additionally the requirement that a page's structure makes sense without CSS seems to indicate that skipping heading levels is not advised. For example:</p>
  
  <pre><code>&lt;h1&gt;...&lt;/h1&gt;
  &lt;h3&gt;...&lt;/h3&gt;
  &lt;h4&gt;...&lt;/h4&gt;
  </code></pre>
  
  <p>A coworker claims that this is fine if the relative importance of the content is reflected in the heading markup. I suppose he could be right.</p>
  
  <p>Thoughts from accessiblity experts?</p>
