title: jQuery FadeIn / FadeOut Methods not working
body: <p>I want to fade the image on hover.
  Why does this not work? </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript"&gt;
    $(document).ready(function(){
      $("#lightbulb").hover(function(){
        $("#lightbulb").fadeOut('fast');
      },function(){
        $("#lightbulb").fadeIn();
      });
    });
  &lt;/script&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Other jQuery methods like CSS styling and changing image sources are working.</p>
