title: what does {% %} mean in html
body: <p>I think it's used to reference php stuff, but I'm not sure. I see some of it written like this in the html file:</p>
  
  <pre><code>{% if ban.reason %}
      &lt;p class="reason"&gt;
          {{ ban.reason }}
      &lt;/p&gt;
  {% endif %}
  </code></pre>
