title: How to add HTML code inside a JS file?
body: <p>I need to include a HTML which adds a preview pane inside a JavaScript function, something like this :</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
      &lt;div style="height: 70%; border: 1px solid #000; overflow: auto;"&gt;
          &lt;div style="background: #ddd; height: 1000px;"&gt;master&lt;/div&gt;
      &lt;/div&gt;
      &lt;div style="height: 30%; border: 1px solid; #000; overflow: auto;"&gt;
          &lt;div style="background: #ddd; height: 1000px;"&gt;detail&lt;/div&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
