title: What is the default font-size of H4?
body: <p>I am completely lost. The website I check for <strong>CSS-defaults</strong> is always <a href="http://www.w3.org/TR/CSS2/sample.html" rel="noreferrer">http://www.w3.org/TR/CSS2/sample.html</a> (I don't trust any other site)</p>
  
  <p>And it seems they missed the <code>font-size</code> of <code>h4</code>.</p>
  
  <p>Sorry to bother you guys for this, but it is important and I don't know how to check it using the tools like <em>firebug</em> or one of those...</p>
