Fade in / Fade Out

Fade in / Fade Out

Hello everyone,

Right not exactly a problem that its not working, at the moment i have a jquery tab box ... at the minute when you click on a tab the page slides in and out. But when i want to do is change it so its a fade in and fade out.

Here is the code for the jquery and the divs / uls that i use for the tabs :

Jquery:
   <script type="text/javascript">
   
     // When the document loads do everything inside here ...
     $(document).ready(function(){
      
      // When a link is clicked
      $("a.tab").click(function () {
         
         // switch all tabs off
         $(".active").removeClass("active");
         
         // switch this tab on
         $(this).addClass("active");
         
         // slide all elements with the class 'content' up
         $(".content").slideUp("slow");
         
         // Now figure out what the 'title' attribute value is and find the element with that id.  Then slide that down.
         var content_show = $(this).attr("title");
         $("#"+content_show).slideDown("slow");
       
      });
   
     });
  </script>


HTML:
<div id="tabbed_box_1" class="tabbed_box">
    <div class="tabbed_area">
   
   <ul class="tabs">
       <li><a href="#" title="Topics" class="tab active">Topics</a></li>
       <li><a href="#" title="content_2" class="tab">Archives</a></li>
       <li><a href="#" title="content_3" class="tab">Pages</a></li>
   </ul>
       
        <div id="Topics" class="content">
           <ul>
               <li><a href="">These will be our forums <small>4 Posts</small></a></li>
         </ul>
        </div>
        <div id="content_2" class="content">
           <ul>
               <li><a href="">These will be the catagorys<small>6 Posts</small></a></li>
   
         </ul>
        </div>
        <div id="content_3" class="content">
           <ul>
               <li><a href="">These will be out settings page</a></li>
         </ul>
        </div>

</div>
 
</div>


Can anyone please help me turn this to fade effect ?

Thanks in advance,
Chris
