Post Views: 5

An image carousel is a slideshow that allows users to cycle through images automatically or manually. It enhances user experience by displaying multiple images in a compact space.

1. What is an Image Carousel?

An image carousel displays a series of images in a rotating manner. It is widely used in websites for showcasing portfolios, product galleries, and advertisements.

2. How to Create an Image Carousel in HTML

To create a simple image carousel, we can use HTML, CSS, and JavaScript. Alternatively, Bootstrap provides a built-in carousel component.

Basic HTML Structure

<div class="carousel">
    <img src="image1.jpg" class="carousel-image" alt="Image 1">
    <img src="image2.jpg" class="carousel-image" alt="Image 2">
    <img src="image3.jpg" class="carousel-image" alt="Image 3">
    <button class="prev" onclick="prevSlide()">&#10094;</button>
    <button class="next" onclick="nextSlide()">&#10095;</button>
</div>

CSS for Styling

.carousel {
    position: relative;
    max-width: 600px;
    overflow: hidden;
}
.carousel-image {
    width: 100%;
    display: none;
}
.carousel-image:first-child {
    display: block;
}
button {
    position: absolute;
    top: 50%;
    transform: translateY(-50%);
    background: rgba(0,0,0,0.5);
    color: white;
    border: none;
    padding: 10px;
}
.prev { left: 0; }
.next { right: 0; }

JavaScript for Functionality

let currentIndex = 0;
const images = document.querySelectorAll(".carousel-image");
function showSlide(index) {
    images.forEach(img => img.style.display = "none");
    images[index].style.display = "block";
}
function prevSlide() {
    currentIndex = (currentIndex === 0) ? images.length - 1 : currentIndex - 1;
    showSlide(currentIndex);
}
function nextSlide() {
    currentIndex = (currentIndex === images.length - 1) ? 0 : currentIndex + 1;
    showSlide(currentIndex);
}

3. Bootstrap Image Carousel

Bootstrap provides a carousel component that simplifies implementation.

<div id="carouselExample" class="carousel slide" data-bs-ride="carousel">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img src="image1.jpg" class="d-block w-100" alt="...">
        </div>
        <div class="carousel-item">
            <img src="image2.jpg" class="d-block w-100" alt="...">
        </div>
        <div class="carousel-item">
            <img src="image3.jpg" class="d-block w-100" alt="...">
        </div>
    </div>
    <button class="carousel-control-prev" type="button" data-bs-target="#carouselExample" data-bs-slide="prev">
        <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    </button>
    <button class="carousel-control-next" type="button" data-bs-target="#carouselExample" data-bs-slide="next">
        <span class="carousel-control-next-icon" aria-hidden="true"></span>
    </button>
</div>
