Automatic Image Carousel in HTML & CSS

This article will guide you on creating an automatic image carousel using HTML and CSS. This method is a simple and lightweight approach for showcasing images in a visually appealing manner, suitable for websites that require a minimal footprint.

HTML Structure

The basic structure for our carousel consists of a container element, and multiple image elements within it. The image container will be styled to create the sliding effect.

In this code:

carousel-container is the main container that holds the entire carousel.
carousel-track contains the images that will slide.

CSS Styling

The CSS will handle the appearance and behavior of our carousel:

.carousel-container {
    width: 400px;
    overflow: hidden;
    position: relative;
}

.carousel-track {
    display: flex;
    transition: transform 0.5s ease-in-out;
}

.carousel-track img {
    width: 100%;
    height: 200px;
    object-fit: cover;
}

This CSS does the following:

Sets a fixed width for the container to control the image size.
Hides any content that overflows the container using overflow: hidden;.
Positions the container for potential future additions like navigation controls.
Uses display: flex; to arrange images in a row.
Applies a smooth transition effect for the sliding animation.
Sets the width and height of images for consistent sizing.

Creating the Sliding Animation

To create the automatic image sliding, we will add more images and use a technique called cloning. We'll duplicate the first image at the end of the track. This allows for a seamless loop when the last image slides out.

.carousel-track {
    display: flex;
    transition: transform 0.5s ease-in-out;
    /* Add this line */
    width: calc(100% * 5); 
}

.carousel-track img {
    width: 20%; /* Adjust this value for image width */
    height: 200px;
    object-fit: cover;
}

Now, add this JavaScript code to the <script> tag in your HTML:

const carouselTrack = document.querySelector('.carousel-track');
let currentPosition = 0;

function slide() {
    currentPosition -= 20;
    carouselTrack.style.transform = `translateX(${currentPosition}%)`;

    if (currentPosition <= -80) {
        currentPosition = 0;
        carouselTrack.style.transform = `translateX(${currentPosition}%)`;
    }
}

setInterval(slide, 3000);

This JavaScript:

Selects the carousel track element.
Initializes a variable currentPosition to track the position.
Defines a slide() function that calculates the new position and applies the translateX transformation.
Creates a loop using setInterval() to call the slide() function every 3 seconds, effectively creating the automatic sliding animation.

Conclusion

With this approach, you've built a basic automatic image carousel using HTML and CSS. You can further customize this by adding navigation buttons, image captions, or more complex animations. This implementation provides a simple and efficient way to showcase images dynamically on your website.
