title: How to set title after html
body: <p>For example you have output <code>&lt;head&gt;</code> tag and don't know <code>title</code> at that moment.</p>
  
  <p>You will know title at the end of code.</p>
  
  <p>How to set title from that place?</p>
  
  <p>Simplified template looks like:</p>
  
  <pre><code>&lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;We don't know title&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;article&gt;
              &lt;!--at this place we include code, that output article and know title--&gt;
          &lt;/article&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Thanks.</p>
