title: Why isn't the summary and detail tag working?
body: <p>I have tried this code here. <code>&lt;details&gt;</code> and <code>&lt;summary&gt;</code> tags are not showing in any of browser I try using. Why?</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;details&gt;
    &lt;summary&gt;StudentResult&lt;/summary&gt;
    &lt;p&gt; The student result are just average...&lt;/p&gt;
  &lt;/details&gt;</code></pre>
  </div>
  </div>
  </p>
