<p>I am using ionic to make a mobile app. I want to add a background to toggle button and range. I used toggle/range-background-dark. It did not work</p>

<pre><code>      &lt;ion-toggle toggle-class="toggle-balanced toggle-background-dark" ng-model="check"&gt;
          33
      &lt;/ion-toggle&gt; 

      &lt;div class="item range range-balanced range-background-dark"&gt;
          &lt;i class="icon ion-ios-sunny-outline"&gt;&lt;/i&gt;
            &lt;input type="range" name="volume" min="0" max="100" ng-model="RV"&gt;
          &lt;i class="icon ion-ios-sunny"&gt;&lt;/i&gt;
      &lt;/div&gt;
</code></pre>
