  <p>Here is my code </p>
  
  <pre><code>&lt;div id="editor1" contenteditable="true"&gt;
      &lt;h1&gt;Inline Editing in Action!&lt;/h1&gt;
      &lt;p&gt;The "div" element that contains this text is now editable.
  &lt;/div&gt;
  &lt;script&gt;
      // Turn off automatic editor creation first.
      CKEDITOR.disableAutoInline = true;
      CKEDITOR.inline( 'editor1' );
  &lt;/script&gt;
  </code></pre>
