Bootstrap 5 Carousel

Welcome back to The Coding College, your go-to platform for coding tutorials! Today, we’ll explore the Bootstrap 5 Carousel, one of the most powerful components for creating image sliders and showcasing content dynamically.

A Carousel is a slideshow component for cycling through elements such as images, text, or custom content. With Bootstrap 5, Carousels are more flexible, responsive, and easier to implement.

Features of Bootstrap 5 Carousel

  • Responsiveness: Adapts beautifully to all screen sizes.
  • Customizable Controls: Add navigation arrows, indicators, captions, and more.
  • Autoplay Support: Easily create auto-sliding carousels.
  • Custom Content: Not limited to images—you can use text, videos, or cards.

Getting Started

1. Include Bootstrap 5

To create a Carousel, you need to include the Bootstrap CSS and JavaScript files. Use a CDN for quick integration:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Bootstrap 5 Carousel</title>
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>

Basic Carousel Example

Here’s the simplest Bootstrap 5 Carousel with images:

<div id="carouselExample" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 1">
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 2">
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 3">
    </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>
    <span class="visually-hidden">Previous</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>
    <span class="visually-hidden">Next</span>
  </button>
</div>

Key Components

  • Carousel Wrapper:
    Add the id and carousel slide classes.
<div id="carouselExample" class="carousel slide" data-bs-ride="carousel">
  • Carousel Items:
    Each slide is wrapped in a carousel-item class. The first item must have the active class. 
<div class="carousel-item active">
    <img src="image1.jpg" class="d-block w-100" alt="Slide 1">
</div>
  • Navigation Controls:
    Add Previous and Next buttons using carousel-control-prev and carousel-control-next.

Adding Indicators

Indicators are small clickable dots for navigating between slides.

<div id="carouselExampleIndicators" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" class="active" aria-current="true"></button>
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="1"></button>
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="2"></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 1">
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 2">
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 3">
    </div>
  </div>
</div>

Customizing the Carousel

1. Autoplay

Add data-bs-ride="carousel" to enable autoplay. By default, slides transition every 5 seconds. Customize the interval:

<div id="carouselExample" class="carousel slide" data-bs-ride="carousel" data-bs-interval="2000">

2. Adding Captions

Captions can be added below the slide image.

<div class="carousel-caption d-none d-md-block">
  <h5>Slide Title</h5>
  <p>Slide Description</p>
</div>

3. Carousel with Controls, Indicators, and Captions

Combine everything for a complete carousel:

<div id="fullCarousel" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button type="button" data-bs-target="#fullCarousel" data-bs-slide-to="0" class="active" aria-current="true"></button>
    <button type="button" data-bs-target="#fullCarousel" data-bs-slide-to="1"></button>
    <button type="button" data-bs-target="#fullCarousel" data-bs-slide-to="2"></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 1">
      <div class="carousel-caption d-none d-md-block">
        <h5>First Slide</h5>
        <p>Description for the first slide.</p>
      </div>
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 2">
      <div class="carousel-caption d-none d-md-block">
        <h5>Second Slide</h5>
        <p>Description for the second slide.</p>
      </div>
    </div>
    <div class="carousel-item">
      <img src="https://via.placeholder.com/800x400" class="d-block w-100" alt="Slide 3">
      <div class="carousel-caption d-none d-md-block">
        <h5>Third Slide</h5>
        <p>Description for the third slide.</p>
      </div>
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#fullCarousel" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#fullCarousel" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
