AngularJS provides built-in support for creating animations using the ngAnimate module. This module provides a way to add animations to your AngularJS applications without having to write custom CSS and JavaScript code.
Let’s break down this topic into the following sections:
- Introduction to Animations in AngularJS
- Animations in AngularJS – Core Concepts
- Creating Animations using ngAnimate
- Example Code Program for Animations in AngularJS
1. Introduction to Animations in AngularJS
Animations in AngularJS are used to add visual feedback to user actions, transitions between states, and element manipulations. These animations can be used to make the user interface more interactive and engaging.
2. Animations in AngularJS – Core Concepts
Before we dive into creating animations using ngAnimate, let’s go over some of the core concepts related to animations in AngularJS:
- CSS Animations and Transitions: AngularJS uses CSS animations and transitions to create animations. These animations are triggered by adding or removing CSS classes on elements in the DOM.
- Animation States: An animation state represents the current state of an element. For example, a button can be in the “default” state or the “active” state.
- Animation Triggers: An animation trigger is an event that causes a state change. For example, clicking a button can trigger a state change from “default” to “active”.
- Animation Timings: Animation timings determine how long an animation takes to complete. This can be controlled using CSS transitions and animations.
3. Creating Animations using ngAnimate
AngularJS provides the ngAnimate module to create animations in your application. This module contains several directives that you can use to add animations to your application. Let’s go over some of the key directives:
- ngAnimate: This directive is used to enable animations in your AngularJS application. You need to include this directive in your HTML element to enable animation support.
- ngAnimateClass: This directive is used to add or remove CSS classes to an element to trigger animations. You can specify different CSS classes for different animation states and triggers.
- ngAnimateChildren: This directive is used to apply animations to child elements when a parent element is animated.
4. Example Code Program for Animations in AngularJS
Here’s an example code program that demonstrates how to create a simple animation using ngAnimate:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<title>Animations in AngularJS</title>
<style>
.fade {
opacity: 1;
transition: opacity 1s;
}
.fade.ng-hide {
opacity: 0;
}
</style>
</head>
<body>
<div ng-controller="myCtrl">
<h1>Animations in AngularJS</h1>
<button ng-click="hide()">Hide</button>
<button ng-click="show()">Show</button>
<p ng-hide="isVisible" class="fade">This paragraph will fade in and out.</p>
</div>

<script>
var app = angular.module('myApp', ['ngAnimate']);
app.controller('myCtrl', function($scope) {
$scope.isVisible = true;
$scope.hide = function() {
$scope.isVisible = false;
};
$scope.show = function() {
$scope.isVisible = true;
};
});
</script>
</body>
</html>
