title: What are the default margins for the html heading tags (<h1>, <h2>, <h3>, etc.)?
body: <p>I avoid using the defaults with the reset code below:</p>
  
  <pre><code>margin:0px; and padding:0px;
  </code></pre>
  
  <p>For example, what are the default margins for the heading tag below?</p>
  
  <pre><code>&lt;h1&gt;Header&lt;/h1&gt;
  </code></pre>
