Diagonal Thumbnails Carousel Using Anime.js

Description:

A pretty cool diagonal thumbnail carousel built using the Anime.js JavaScript library.

It takes a group of images and converts them into carousel UI where you can switch between thumbnails in the diagonal direction.

How to use it:

1. Insert your images into the thumbnail grids.

<div class="slider">
  <div class="nav">
    <div class="next"></div>
    <div class="prev"></div>
    <div class="explore-btn">Explore</div>
  </div>
  <div class="item is-active">
    <div class="content">
      <div class="wrap">Novitates</div>
    </div>
    <div class="imgs">
      <div class="grid">
        <div class="img img-1"><img src="1.jpg"/></div>
        <div class="img img-2"><img src="2.jpg"/></div>
        <div class="img img-3"><img src="3.jpg"/></div>
        <div class="img img-4"><img src="4.jpg"/></div>
      </div>
    </div>
  </div>
  <div class="item">
    <div class="content">
      <div class="wrap">Si spem</div>
    </div>
    <div class="imgs">
      <div class="grid">
        <div class="img img-1"><img src="1.jpg"/></div>
        <div class="img img-2"><img src="2.jpg"/></div>
        <div class="img img-3"><img src="3.jpg"/></div>
        <div class="img img-4"><img src="4.jpg"/></div>
      </div>
    </div>
  </div>
  <div class="item">
    <div class="content">
      <div class="wrap">Adferunt</div>
    </div>
    <div class="imgs">
      <div class="grid">
        <div class="img img-1"><img src="1.jpg"/></div>
        <div class="img img-2"><img src="2.jpg"/></div>
        <div class="img img-3"><img src="3.jpg"/></div>
        <div class="img img-4"><img src="4.jpg"/></div>
      </div>
    </div>
  </div>
</div>

3. Add the required anime.js JavaScript library to the page.

<script src="/path/to/cdn/anime.min.js"></script>

4. The main script to enable the diagonal carousel.

function init() {
  const slider = document.querySelector(".slider");
  const nextBtn = slider.querySelector(".slider .nav .next");
  const prevBtn = slider.querySelector(".slider .nav .prev");
  const items = slider.querySelectorAll(".slider .item");

  let current = 0;

  items.forEach(item => {
    const textWrapper = item.querySelector(".wrap");
    textWrapper.innerHTML = textWrapper.textContent.replace(
    /\S/g,
    "$&");

  });

  function anim(current, next, callback) {
    const currentImgs = current.querySelectorAll(".img");
    const currentText = current.querySelectorAll(".content .letter");
    const nextImgs = next.querySelectorAll(".img");
    const nextText = next.querySelectorAll(".content .letter");

    const duration = 400;
    const offset = "-=" + 300;
    const imgOffset = duration * .8;

    const tl = anime.timeline({
      easing: "easeInOutQuint",
      duration: duration,
      complete: callback });


    // Add children
    tl.add({
