How to toggle character sheet or rpg

In phbb3, how can i make a toggle for the character sheet and other excess info in the profile to save some space?

Like shrink it?

Bump?

I used this code to show or hide some portions of the profile but I can't make it work. I'm using phbb3

Code:

<script src="http://code.jquery.com/jquery-latest.js"></script>
 
  <script>
  $(document).ready(function(){
   
    $("button1").click(function () {
      $("t").toggle("slow");
    });   

  });</script>
