title: Can I nest these tags?
body: <p>I hear that using a <code>&lt;p&gt;</code> tag inside an <code>&lt;h1&gt;</code> tag is wrong, and that using a <code>&lt;p&gt;</code> tag inside another <code>&lt;p&gt;</code> tag is also wrong. Is that the case?</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;body&gt;
  
  &lt;h1&gt;There was &lt;p&gt;before us a long &lt;h3&gt;piece &lt;/h3&gt; of level road by the &lt;/p&gt;riverside.&lt;/h1&gt;
  
  &lt;p&gt;John said to me, &lt;b&gt;"Now, &lt;p&gt;Beauty&lt;/p&gt;, do your best"&lt;/b&gt; and so I did&lt;/p&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
