Style Bootstrap 4 Custom Checkbox : <p>How do I style a custom checkbox in Bootstrap 4? I've tried everything but I can't even change its background color.</p>

<p>This is my code outline:</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;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous"&gt;
&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;Check this custom checkbox&lt;/span&gt;
&lt;/label&gt;</code></pre>
</div>
</div>
</p>

<p>What do I target here? Could someone just show me how to change its background?</p>

<p>Thank you.</p>
