title: Very simple toggleClass not working
body: <p>So I have some really simple code but it's not working.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$(function() {
   $("#tren").click(function() {
    $("#trens").toggleClass("show");
   });
  });</code></pre>
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.show {
      color: "red";
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;ul&gt;
      &lt;li id="tren"&gt;Some text&lt;/li&gt;
  &lt;/ul&gt;
  &lt;div id="trens"&gt;
      &lt;p&gt;Other text&lt;/p&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>'Other text' is supposed to get red, but it doesn't . What am I doing wrong?</p>
