title: ng5-slider - How can we change background-color of slider-active?
body: <p>I would like to change the background-color of the active pointer ?</p>
  <p><a href="https://i.stack.imgur.com/aLU4L.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aLU4L.png" alt="Default background-color is #451AFF" /></a></p>
  <p>In Chrome's inspector I can change it, the class is :</p>
  <pre><code>.ng5-slider-active::after { background-color: #451AFF; }
  </code></pre>
  <p>But I can't do the same in my <strong>css file</strong>.</p>
  <p>I tried this but that doesn't seem to work :</p>
  <pre><code>::ngdeep {
    .custom-slider .ng5-slider .ng5-slider-pointer .ng5-slider-active::after {
      background-color: #fff!important;
    }
  }
  </code></pre>
