    <script src="script.js" defer></script>
    <section class="wrapper">
      <i class="fa-solid fa-arrow-left button" id="prev"></i>
      <div class="image-container">
        <div class="carousel">
          <img src="images/image1.jpg" alt="" />
          <img src="images/image2.jpg" alt="" />
          <img src="images/image3.jpg" alt="" />
          <img src="images/image4.jpg" alt="" />
        <i class="fa-solid fa-arrow-right button" id="next"></i>

Second, paste the following codes into your style.css file.

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
body {
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  background: #343f4f;
.wrapper {
  display: flex;
  max-width: 650px;
  width: 100%;
  height: 400px;
  background: #fff;
  align-items: center;
  justify-content: center;
  position: relative;
  border-radius: 12px;
  box-shadow: 0 5px 10px rgba(0, 0, 0, 0.1);
.wrapper i.button {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  height: 36px;
  width: 36px;
  background-color: #343f4f;
  border-radius: 50%;
  text-align: center;
  line-height: 36px;
  color: #fff;
  font-size: 15px;
  transition: all 0.3s linear;
  z-index: 100;
  cursor: pointer;
i.button:active {
  transform: scale(0.94) translateY(-50%);
i#prev {
  left: 25px;
i#next {
  right: 25px;
.image-container {
  height: 320px;
  max-width: 500px;
  width: 100%;
  overflow: hidden;
.image-container .carousel {
  display: flex;
  height: 100%;
  width: 100%;
  transition: all 0.4s ease;
.carousel img {
  height: 100%;
  width: 100%;
  border-radius: 18px;
  border: 10px solid #fff;
  object-fit: cover;

Third, paste the following codes into your script.js file.

// Get the DOM elements for the image carousel
const wrapper = document.querySelector(".wrapper"),
  carousel = document.querySelector(".carousel"),
  images = document.querySelectorAll("img"),
  buttons = document.querySelectorAll(".button");

let imageIndex = 1,

// Define function to start automatic image slider
const autoSlide = () => {
  // Start the slideshow by calling slideImage() every 2 seconds
  intervalId = setInterval(() => slideImage(++imageIndex), 2000);
// Call autoSlide function on page load

// A function that updates the carousel display to show the specified image
const slideImage = () => {
  // Calculate the updated image index
  imageIndex = imageIndex === images.length ? 0 : imageIndex < 0 ? images.length - 1 : imageIndex;
  // Update the carousel display to show the specified image = `translate(-${imageIndex * 100}%)`;

// A function that updates the carousel display to show the next or previous image
const updateClick = (e) => {
  // Stop the automatic slideshow
  // Calculate the updated image index based on the button clicked
  imageIndex += === "next" ? 1 : -1;
  // Restart the automatic slideshow

// Add event listeners to the navigation buttons
buttons.forEach((button) => button.addEventListener("click", updateClick));

// Add mouseover event listener to wrapper element to stop auto sliding
wrapper.addEventListener("mouseover", () => clearInterval(intervalId));
// Add mouseleave event listener to wrapper element to start auto sliding again
wrapper.addEventListener("mouseleave", autoSlide);
