  box-sizing: border-box;

body {
  display: flex;
  align-items: center;
  justify-content: center;

Finally, add the following JavaScript code to your script.js file to make your image slider functional.

const initSlider = () => {
    const imageList = document.querySelector(".slider-wrapper .image-list");
    const slideButtons = document.querySelectorAll(".slider-wrapper .slide-button");
    const sliderScrollbar = document.querySelector(".container .slider-scrollbar");
    const scrollbarThumb = sliderScrollbar.querySelector(".scrollbar-thumb");
    const maxScrollLeft = imageList.scrollWidth - imageList.clientWidth;
    // Handle scrollbar thumb drag
    scrollbarThumb.addEventListener("mousedown", (e) => {
        const startX = e.clientX;
        const thumbPosition = scrollbarThumb.offsetLeft;
        const maxThumbPosition = sliderScrollbar.getBoundingClientRect().width - scrollbarThumb.offsetWidth;
        // Update thumb position on mouse move
        const handleMouseMove = (e) => {
            const deltaX = e.clientX - startX;
            const newThumbPosition = thumbPosition + deltaX;

            // Ensure the scrollbar thumb stays within bounds
            const boundedPosition = Math.max(0, Math.min(maxThumbPosition, newThumbPosition));
            const scrollPosition = (boundedPosition / maxThumbPosition) * maxScrollLeft;
   = `${boundedPosition}px`;
            imageList.scrollLeft = scrollPosition;

        // Remove event listeners on mouse up
        const handleMouseUp = () => {
            document.removeEventListener("mousemove", handleMouseMove);
            document.removeEventListener("mouseup", handleMouseUp);

        // Add event listeners for drag interaction
        document.addEventListener("mousemove", handleMouseMove);
        document.addEventListener("mouseup", handleMouseUp);

    // Slide images according to the slide button clicks
    slideButtons.forEach(button => {
        button.addEventListener("click", () => {
            const direction = === "prev-slide" ? -1 : 1;
            const scrollAmount = imageList.clientWidth * direction;
            imageList.scrollBy({ left: scrollAmount, behavior: "smooth" });

     // Show or hide slide buttons based on scroll position
    const handleSlideButtons = () => {
        slideButtons[0].style.display = imageList.scrollLeft <= 0 ? "none" : "flex";
        slideButtons[1].style.display = imageList.scrollLeft >= maxScrollLeft ? "none" : "flex";

    // Update scrollbar thumb position based on image scroll
    const updateScrollThumbPosition = () => {
        const scrollPosition = imageList.scrollLeft;
        const thumbPosition = (scrollPosition / maxScrollLeft) * (sliderScrollbar.clientWidth - scrollbarThumb.offsetWidth); = `${thumbPosition}px`;

    // Call these two functions when image list scrolls
    imageList.addEventListener("scroll", () => {

window.addEventListener("resize", initSlider);
window.addEventListener("load", initSlider);
