title: jQuery show/hide div from bottom to top
body: <p>Yo all!</p>
  
  <p>I am new with jQuery and I want to know how can I show/hide a div using fadeIn and FadeOut and at the same time an animation bottom to top and top to bottom. </p>
  
  <p>I tried with this: <a href="http://jsfiddle.net/jalxob/kNL5m/2/" rel="nofollow">http://jsfiddle.net/jalxob/kNL5m/2/</a></p>
  
  <p>But it also shows a {"error": "Please use POST request"}</p>
  
  <p>Can anyone please help me?</p>
  
  <pre><code>$('.hello').click(function() {
  $(".content_b").fadeIn();
  $(".content_b_content").animate({marginTop:"-=100px"},300);
  </code></pre>
