    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"></script>
    <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

    .myFocus {
        background-color: lightgreen;
    }

        background-color: pink;
    }
</style>
</head>
<body ng-app="app">
    <div ng-controller="controllerName">
        <div class="container">
            Ng-Focus:  <input class="form-control" type="text" ng-class="{true:'myFocus',false:'blur' }[focus]" ng-focus="focus=true" ng-blur="focus=false">
            Focus: {{focus}}
        </div>
    </div>
    <script>
    var app = angular.module("app", []);
    app.controller('controllerName', ['$scope', function ($scope) {

    }]);
</script>
</body>
