title: Default jQuery fade animation method not using the default fx queue?
body: <p>I've wrote my first jQuery script that animate multiple "wall" of images with a HTML like this: </p>
  
  <pre><code>&lt;div id="home-wall"&gt;
      &lt;div class="wall" animation-order="default"&gt;
          &lt;div class="uk-grid grid uk-grid-preserve wk-gallery wk-gallery-wall zoom"&gt;
              &lt;a class="" href=""&gt;&lt;img src="gallery/zoom/image1.jpg"&gt;&lt;/a&gt;
              &lt;a class="" href=""&gt;&lt;img src="gallery/zoom/image2.jpg"&gt;&lt;/a&gt;
              &lt;a class="" href=""&gt;&lt;img src="gallery/zoom/image3.jpg"&gt;&lt;/a&gt;
              &lt;a class="" href=""&gt;&lt;img src="gallery/zoom/image4.jpg"&gt;&lt;/a&gt;
              &lt;a class="" href=""&gt;&lt;img src="gallery/zoom/image5.jpg"&gt;&lt;/a&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="wall" animation-order="default"&gt;
      ....
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Still I don't get why when I use a call like this (in the script or directly in the Firebug console)</p>
  
  <pre><code>jQuery(".wall").first().fadeOut(400).next().fadeIn(400);
  </code></pre>
  
  <p>the fade animation doesn't seems to queue in the default <code>fx</code> queue <a href="http://api.jquery.com/queue/#queue2" rel="nofollow">like the docs says</a>, but happen simultaneously. I'm expecting to first see the fade out of the first wall and only when it's completely hid (<code>display:none</code>) seeing the next wall fade in.</p>
  
  <p>What I didn't understand? Have I to create a a custom animation queue?</p>
