  Here is a basic <abbr title="Hypertext Markup Language">HTML</abbr> document:
</p>
<pre>
&lt;!DOCTYPE html&gt;
&lt;html class=&quot;no-js&quot; lang=&quot;en&quot;&gt;
&lt;head&gt;
  &lt;meta charset=&quot;utf-8&quot;&gt;
  &lt;title&gt;An HTML Page&lt;/title&gt;
&lt;/head&gt;

&lt;body&gt;
  &lt;h1&gt;A Heading With Some &amp;quot;Quotes&amp;&quot;&lt;/h1&gt;
&lt;/body&gt;

&lt;/html&gt;
</pre>

<h1>The Visible Title of Your Page</h1>

<p class="lead">
  A summary of the page perhaps would go here. Whatever, really.
</p>

<h2>A 2nd-level subheading</h2>
<p>
  Some content and media or whatever.
</p>

<h3>A sub-subheading</h3>
<p>
  This section appears under the 2nd level.
</p>

<h4>A sub-sub-subheading</h4>
<p>
  I hope you're getting the point now.
</p>

<h2>We're back at the 2nd level</h2>
<p>
  And this could have its own subsections as well...
</p>
