• Excellent Learning Curve: Anime.js is easy to learn, even for beginners. With a basic understanding of CSS and JavaScript, you can create stunning animations.

Simple Animation Example

Let’s create a simple animation example using Anime.js. We’ll animate four divs to move down and then back up.

<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>

/* style.css */
.box {
  width: 100px;
  height: 100px;
  margin: 4px;
  display: inline-block;
  background-color: #ff69b4;
}

// main.js
anime({
  targets: '.box',
  translateY: [
    { value: 200, duration: 500 },
    { value: 0, duration: 500 }
  ],
  rotate: '1turn',
  easing: 'easeInOut',
  delay: anime.stagger(200),
  loop: true
});

Building a Background Animation

Let’s create a more complex animation example using Anime.js. We’ll create a background animation with hundreds of divs moving in a wave-like motion.

<div class="container"></div>

/* style.css */
.container {
  position: relative;
  width: 100%;
  height: 100vh;
  background-color: #f0f0f0;
}

.block {
  position: absolute;
  width: 10px;
  height: 10px;
  background-color: #333;
}

// main.js
const container = document.querySelector('.container');

for (let i = 0; i < 100; i++) {
  const block = document.createElement('div');
  block.classList.add('block');
  container.appendChild(block);
}

anime({
  targets: '.block',
  translateX: [
    { value: 100, duration: 500 },
    { value: 0, duration: 500 }
  ],
  translateY: [
    { value: 100, duration: 500 },
    { value: 0, duration: 500 }
  ],
  easing: 'easeInOut',
  delay: anime.stagger(20),
  loop: true
});
