title: combining jquery .before() and .slideDown() or duration
body: <p>I have a list of comments. After a user submit a new comment, I'd like the newly submitted comment to display before the add-comment form. I've got it to work so far, but I'd like the .before to be an animation.</p>
  
  <p>More specifically, I'm trying to get the .before() action to animate/slide instead of just displaying. I currently have the follow code which is working for displaying.</p>
  
  <pre><code>el.find(".add-comment").before(new_comment);
  </code></pre>
  
  <p>I looked at jquery .before() and don't see a duration parameter. I also tried this but it doesn't work:</p>
  
  <pre><code>el.find(".add-comment").before(new_comment).slideDown();
  </code></pre>
  
  <p>Any suggestions?</p>
