Bootstrap 4 Carousel 的幻燈片默認(rèn)是滑動過渡的，如果你想更改為淡入淡出過渡，那么可以參考下本文介紹的方法。

Bootstrap 4 Carousel

為此，我們需要對 HTML 代碼進(jìn)行的唯一更改是將類添加carousel-fade到主輪播 div。在我們的示例中，它是帶有 ID 元素的 div my-carousel。接下來，我們只需復(fù)制并粘貼下面的 CSS 代碼，就可以了！

HTML

<div id="my-carousel" class="carousel slide carousel-fade" data-ride="carousel" data-interval="5000">
    <ol class="carousel-indicators">
        <li data-target="#my-carousel" data-slide-to="0" class="active"></li>
        <li data-target="#my-carousel" data-slide-to="1"></li>
        <li data-target="#my-carousel" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img class="d-block w-100" src="1.jpg" alt="First slide">
        </div>
        <div class="carousel-item">
            <img class="d-block w-100" src="2.jpg" alt="Second slide">
        </div>
        <div class="carousel-item">
            <img class="d-block w-100" src="3.jpg" alt="Third slide">
        </div>
    </div>
    <a class="carousel-control-prev" href="#my-carousel" role="button" data-slide="prev">
        <span class="carousel-control-prev-icon" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a>
    <a class="carousel-control-next" href="#my-carousel" role="button" data-slide="next">
        <span class="carousel-control-next-icon" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
    </a>
</div>

CSS

.carousel-fade .carousel-item {
  opacity: 0;
  transition-duration: .6s;
  transition-property: opacity;
}

.carousel-fade .carousel-item.active,
.carousel-fade .carousel-item-next.carousel-item-left,
.carousel-fade .carousel-item-prev.carousel-item-right {
  opacity: 1;
}

.carousel-fade .active.carousel-item-left,
.carousel-fade .active.carousel-item-right {
  opacity: 0;
}

.carousel-fade .carousel-item-next,
.carousel-fade .carousel-item-prev,
.carousel-fade .carousel-item.active,
.carousel-fade .active.carousel-item-left,
.carousel-fade .active.carousel-item-prev {
  transform: translateX(0);
  transform: translate3d(0, 0, 0);
}
