How to create Timeline Animations using Anime.js ?

Last Updated : 26 Jul, 2024

Anime.js is a lightweight JavaScript library with a simple and small powerful API. It works with the DOM element, CSS, and JavaScript object.

Prerequisites

Installation of anime.js: There are two ways to use anime.js in your project:

You can download the anime.min.js file and directly use it.
Just google anime.js CDN and you will get the link and just put it in your script tag as shown below.

<script src=”https://cdnjs.cloudflare.com/ajax/libs/animejs/3.2.0/anime.min.js”></script>

Basic Properties used in anime.js:

targets: The CSS Selectors to target and identify on which animation has to apply.
duration: Time in milliseconds for which animation should last.
delay: Time in milliseconds after which animation starts.
translateX: Places element at that x coordinate.
translateY: Places element at Y coordinate.
offset: This gives a delay between different animations. i.e. to start another animation after x seconds of the previous one.

Creating an application and Project structure: This is a simple web page. All we need to do is create a project and inside it create an HTML File named index.html.

mkdir animation && cd animation
touch index.html

Example 1:

HTML

<!DOCTYPE html>
<html>

<head>
    <title>A nice example for timeline</title>
    <script src=
"https://cdnjs.cloudflare.com/ajax/libs/animejs/3.2.0/anime.min.js">
    </script>
    <style>
        html {
            min-height: 200vh;
        }

        .ball {
            width: 60px;
            height: 60px;
            margin-top: 120px;
            margin-left: 200px;
            border-radius: 50%;
            background-color: pink;
            float: left;
        }
    </style>
</head>

<body>
    <div class="ball first"></div>
    <div class="ball second"></div>
    <div class="ball third"></div>
    <script>
        let animation = anime.timeline({
            duration: 500,
            easing: 'easeInOutSine',
            direction: 'alternate',
            autoplay: false,
            loop: true
        });

        animation.add({
            targets: '.first',
            translateY: -50,
            backgroundColor: 'rgb(255, 0, 0)'
        }).add({
            targets: '.second',
            translateY: -50,
            backgroundColor: 'rgb(0, 255, 0)'
        }).add({
            targets: '.third',
            translateY: -50,
            backgroundColor: 'rgb(0, 0, 255)'
        });
        window.onscroll = () => {
            animation.play();
        }
    </script>

</body>

</html>

Output:

Example 2: In this example, the translateX property becomes more clear. It first translates into -ve x axis and then +ve x axis.
