Make sure to give an item a little extra attention by highlighting or making it blink after it has

I have a collection of items that I utilize to construct an unordered list using ng-repeat. When a new item is added, I want it to stand out by blinking or having some kind of effect to grab the user's attention. While it would be easy with jQuery, I am determined to achieve this using AngularJS alone.

index.html

<!DOCTYPE html>
<html ng-app="app">

  <head>
    <link rel="stylesheet" href="style.css">
     <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
     <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular-animate.min.js"></script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Hello Plunker!</h1>
    <div ng-controller="MainCtrl">
      <input type="text" ng-model="formData.itemText" />
      <button ng-click="addItem()">Add</button>
      <ul>
        <li ng-repeat="item in items">{{item.itemText}}</li>
      </ul>
    </div>
  </body>

</html>

script.js

app = angular.module("app", ["ngAnimate"])

app.controller("MainCtrl", function($scope){
  $scope.items = []
  $scope.formData = {}
  $scope.addItem = function(){
    $scope.items.push($scope.formData)
    $scope.formData = {}
  }
})

Exploring the methods outlined in the resource can help achieve this goal through various approaches.

Here is a straightforward illustration:

.highlight {
  transition: all linear 300ms;
}
.highlight.ng-enter {
  opacity: 0;
  color: firebrick;
}
.highlight.ng-enter.ng-enter-active {
  opacity: 1;
}

Additionally, consider this snippet:

<li ng-repeat="item in items" class="highlight">
