title: Find a class inside the parent of a clicked element
body: <p>I'm trying to find the class .post-info inside the parent of a clicked element, .toggle-info. Right now all the .post-info's on the page toggle. I'm trying to get only that one .post-info to toggle inside it's parent container, .post.</p>
  
  <pre><code>&lt;div class="post"&gt;
   &lt;div class="toggle-info"&gt;Toggle Btn&lt;/div&gt;
  
   &lt;div class="post-info"&gt;
    &lt;p&gt;Toggle this content&lt;/p&gt;
   &lt;/div&gt;
  
  &lt;/div&gt;
  
  
  $(".toggle-info").click(function () {   
    $(".post-info").animate({ 
      height: "toggle",
      opacity:"toggle"
    }, 520, 'swing');
  });
  </code></pre>
  
  <p>Thanks in advance for the help!</p>
