title: Add to DOM without jQuery
body: <p>This should be simple, but it's not.</p>
  
  <pre><code>document.getElementsByTagName('body')[0].document.createTextNode( document.createElement('&lt;div&gt;some HTML&lt;/div&gt;') );
  </code></pre>
  
  <p>It creates as a text node. How do I do it so I simply add HTML without jQuery?</p>
