title: How to set background color IONIC 4
body: <p>I having problems trying to change the background color in just one IONIC 4 (--type=angular) page. I am trying to add a class for the ion-content. In my html file I Have:</p>
  
  <pre><code>&lt;ion-content class="fondologin"&gt;
  ...
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>In my sass I have:</p>
  
  <pre><code>.fondologin{
      background-color: #111D12!important;
  }
  </code></pre>
  
  <p>The background color is never changed. If I add --ion-background-color:#111D12; in variables.scss the background is successfully changed for every page but I just one to change the color in one page. How can I achieve this?</p>
