title: Adding HTML elements with JavaScript
body: <p>So, if I have HTML like this:</p>
  
  <pre><code>&lt;div id='div'&gt;
    &lt;a&gt;Link&lt;/a&gt;
  
    &lt;span&gt;text&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How can I use JavaScript to add an HTML element where that blank line is?</p>
