title: How to change opacity of all Ionic pop-ups
body: <p>How can I change the opacity of all Ionic pop-ups in my project? i.e. <code>$ionicPopup.show()</code>. I've tried adding the following entries to <code>www/style.css</code> in various combinations but to no avail.</p>
  
  <pre><code>.popup {
    opacity: 1.0;
  }
  
  .popup-body {
    opacity: 1.0;
  }
  
  .popup {
    opacity: 1.0 !important;
  }
  
  .popup-body {
    opacity: 1.0 !important;
  }
  </code></pre>
