title: Custom checkbox without indicator (text)
body: <p>I'm trying to get a custom checkbox without the indicator like this:</p>
  
  <pre><code>&lt;label class="custom-control custom-checkbox"&gt;
    &lt;input type="checkbox" class="custom-control-input"&gt;
    &lt;span class="custom-control-indicator"&gt;&lt;/span&gt;
    &lt;span class="custom-control-description"&gt;&lt;/span&gt;
  &lt;/label&gt;
  </code></pre>

  <p>As you can see, the checkbox doesn't work. But if you add text:</p>
  
  <pre><code>&lt;label class="custom-control custom-checkbox"&gt;
    &lt;input type="checkbox" class="custom-control-input"&gt;
    &lt;span class="custom-control-indicator"&gt;&lt;/span&gt;
    &lt;span class="custom-control-description"&gt; Checkbox&lt;/span&gt;
  &lt;/label&gt;
  </code></pre>

  <p>It works. How can I fix that?</p>
