AngularJS incorporating dynamic stylesheets

I am facing a challenge with my AngularJS application as it fetches data via an API and dynamically builds a webpage.

Typically, I rely on ng-style for dynamic styling, but now I need to utilize the nth-of-type attribute which can only be applied in a CSS stylesheet (as the number and order of elements are always changing).

I attempted the following code snippet (within the HTML page):

<style ng-if="styles.sc && styles.sc.length==3">
    a.mosection:nth-of-type(3n) > div {
        background-color: {{styles.sc[0]}} !important;
    }
    a.mosection:nth-of-type(3n+1) > div {
        background-color: {{styles.sc[1]}} !important;
    }
    a.mosection:nth-of-type(3n+2) > div {
        background-color: {{styles.sc[2]}} !important;
    }
</style>

Unfortunately, this approach did not yield the desired result. It seems that Angular does not bind the data within the style tag (although the ng-if attribute is properly digested).

If anyone has any insights on how to achieve this, I would greatly appreciate your assistance!

Thank you!

Appreciate it! I managed to resolve it by utilizing ng-style in combination with a function

The Markup

<div class="widget widget-people" ng-style="{backgroundColor: staggerBgColors('widget', 'widget-people', '#333333')}"></div>
<div class="widget widget-property" ng-style="{backgroundColor: staggerBgColors('widget', 'widget-property', '#24d10f')}"></div>

The scope function

$scope.staggerBgColors = function(elesClass, eleClass, defaultColor){
  if (!$scope.styles || !$scope.styles.sc || $scope.styles.sc.length!=3){
    return defaultColor;
  }else{
    var listItem = $('.'+eleClass);
    var n = $('.'+elesClass).index( listItem ) % 3;
    return '#' + $scope.preview.moment.sc[n];
  }
}

I had to recreate the functionality of the css property "nth-of-type" using jQuery, but it performs flawlessly!
