title: How to indent HTML tag content
body: <p>Maybe this is a too basic question.</p>
  
  <pre><code>&lt;p&gt;A long text here A long text here A long text here A long text here A long text here A long text here A long text here A long text here &lt;/p&gt;
  </code></pre>
  
  <p>Is it possible to write something like:</p>
  
  <pre><code>&lt;p&gt;A long text here A long text here A long text here 
    A long text here ...
    ...
  &lt;/p&gt;
  </code></pre>
  
  <p>Also, help me tagging this question.</p>
