Tips for incorporating a smooth fade in and out effect into images within a Bootstrap 5 carousel

I'm currently working with a Bootstrap 5 carousel and trying to implement a transition effect where clicking the "next" arrow will smoothly fade out the current image before fading in the next one. This is necessary because the images in my carousel vary in size, making the abrupt transition look unappealing.

This is the current setup:

<body style="max-width: 100%; overflow-x:hidden; background-color:black;">
    <div class="container-lg">

            <div class="col-4">
                <div id="myCarousel" class="carousel slide carousel-fade">
                    <div class="carousel-inner">
                        <div class="carousel-item active img-fluid">
                            <img src = "image1.jpg" class = "img-fluid">

                        <div class="carousel-item img-fluid">

                    </div>                 
                </div>
                <button class="carousel-control-prev" onclick="nextSlide()" type="button" data-bs-target="#myCarousel" 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" onclick="nextSlide()" type="button" data-bs-target="#myCarousel" data-bs-slide="next">
                    <span class="carousel-control-next-icon" aria-hidden="true"></span>
                    <span class="visually-hidden">Next</span>
                </button>
            </div>
        </div>
    </div>
    <script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="14767b7b60676066756454213a273a26">[email protected]</a>/dist/js/bootstrap.bundle.min.js" integrity="sha384-C6RzsynM9kWDrMNeT87bh95OGNyZPhcTNXj1NW7RuBCsyN/o0jlpcV8Qyq46cDfL" crossorigin="anonymous"></script>
</body>
</html>

Below is my custom CSS:

.carousel-item {
    width: 100%;
    height: 100%;
    overflow: hidden;
}
.fadeIn {
    visibility: visible;
    opacity: 1;
    transition: opacity 2s linear;
}
.fadeOut {
visibility: hidden;
opacity: 0;
transition: visibility 0s 2s, opacity 2s linear;
}

And here's the JavaScript function I'm using:

function nextSlide() {
    const carousel = document.getElementById('myCarousel');
    const activeItem = carousel.querySelector('.carousel-item.active');
    const nextItem = activeItem.nextElementSibling || carousel.querySelector('.carousel-item:first-child');
    setTimeout(() => {
      activeItem.classList.remove('active');
      activeItem.classList.add("fadeOut");
      activeItem.classList.remove("fadeIn");
      nextItem.classList.add('active');
      nextItem.classList.remove("fadeOut");
      nextItem.classList.add("fadeIn")
    }, 3000);
}

Answer №1

Bootstrap 5 comes with a default fade in/out effect on slides using the carousel-fade class, as demonstrated below in a live demo.

If you wish to enhance the fade in/out functionality further in your code, you will need to utilize the events provided by the Bootstrap 5 carousel rather than creating custom events...

To access the values passed via these Bootstrap 5 carousel JavaScript events...

Refer to the documentation here: https://getbootstrap.com/docs/5.3/components/carousel/#events

Check the console for logged events from the carousel...

const myCarousel = document.getElementById('myCarousel');

myCarousel.addEventListener('slide.bs.carousel', event => {

  console.clear();

  console.log(event.direction, event.relatedTarget, event.from, event.to);

});
...




CSS only solution update...

Upon reviewing your question, it seems that you simply want each .carousel-item to completely fade out before the next or previous slide fades in.

This can be achieved through CSS overrides to the transition property, controlling the duration and delay of the opacity transition effect.

See an example of CSS-only overrides for the Bootstrap 5.3 carousel below...

#myCarousel .active.carousel-item-end, 
#myCarousel .active.carousel-item-start {
  transition-duration: 600ms;
  transition-delay: 0ms;
}

#myCarousel .carousel-item-next, 
#myCarousel .carousel-item-prev {
  transition-duration: 600ms;
  transition-delay: 600ms;
}
...


Remember to set the data-bs-interval attribute to at least 1200ms (1.2 seconds) to prevent overlapping slides during the fade-in/fade-out transitions when using

data-bs-ride="carousel"
.

If you want a custom interval time between auto transitions, add your desired interval time to 1200ms. For instance, setting an interval time of 3 seconds would require

data-bs-interval="4200"
.

For more detailed explanation, feel free to check the updated CSS examples above.
