title: Ionic: how to use cssClass in $ionicPopup?
body: <p>So I want to modify the default width in $ionicPopup and to do so I have to add 'cssClass' to my popup object just like the code below</p>
  
  <pre><code>  $scope.getScore = function(){
    var popupScore = $ionicPopup.alert({
  
    title:'Score',
    template: 'Total XP points: 50',
    cssClass: '',
    buttons: [{
      text:'Return',
      type: 'button-assertive'
    }]}}
  </code></pre>
  
  <p>How would you proceed in this case? Should I give cssClass a value? (i.e: cssClass = 'popupClass') and then go to my CSS file and modify the width from there?</p>
