I am trying to make a sort of "scales" look, where two divs will slowly animate up and down like being weighed on a scale. I could use some help with the functions though please, I can not get two to animate simultaneously on page load, and I need them to go up, then back down, then up, etc... Make sense? Here is what I have so far, I am kinda new to jquery obviously, :) 
Thanks for any help!

```
<style type='text/css'>
  body {
    background: #262626;    
  }
  .main 
  {
    margin: 20px auto;
    position:relative;    
    height:400px;    
    width:300px; 
  } 
  .content 
  {
    float: left;
    position:absolute; 
    bottom: 10px;   
    left: 100px;
    height:40px;    
    width: 100px;    
  } 
  .content2 
  {
    float: left;
    position:absolute; 
    top: 10px;   
    left: 100px;
    height:40px;    
    width: 100px;    
  }
</style>

        $(".content2").animate({bottom:'10px'},{ queue:true, duration:3000 });          
    });
</script>

    <div class="content2">

</div>
