Read more button for tumblr
<p>Good Morning!
I would like to ask your help for solving this problem:
I want to add a read more button to my tumblr blog, but the one what the site provides isn't right for my goals. I need the button to toggle the 'closed' class on the appropriate 'body-text' class element.</p>

<p>I have this code:</p>

<pre><code> ._readmore {
        width: 100%;
        height: 20px;
        text-align: center;
        margin-top: 20px;
        margin-bottom: 0px;
        cursor: pointer;
    }
    .closed {
        max-height: 100px;
        overflow-y: hidden;
    }



  $(document).ready(function(){
       $("._readmore").click(function(){
         $(".body-text").toggleClass("closed");
       });
    });
</code></pre>

<p>The problem is, if i click one of the '_readmore' class elements all of the 'body-text' class elements will loose the closed class.</p>
