Question

我在轮播中滚动效果时遇到问题。只是动画，简单的滚动工作，而动画则没有。也许有人可以检查我的代码并修复^ _ ^谢谢。 image使用类carousel-image-1（2,3）添加CSS。我比较了官方引导站点上的示例，并且都比较了我的代码。也许我看不到错误

.carousel-item {
  height: 450px;
}

.carousel-image-1 {
  background: url(https://source.unsplash.com/random/560x560);
  background-size: cover;
}

.carousel-image-2 {
  background: url(https://source.unsplash.com/random/560x560);
  background-size: cover;
}

.carousel-image-3 {
  background: url(https://source.unsplash.com/random/560x560);
  background-size: cover;
}

我添加了样式...请检查一下

Answer 2

您只需要为滑块指定一个高度-默认高度为0像素。 :-)

如下所示，我刚刚添加了400px的min-height（您可以将其设置为任意值），并且还设置了随机背景，以便您可以看到白色文本（因为它没有出现在您的示例中，但是滑块实际上是在幕后工作。

.carousel-item {
  min-height: 400px;
  background-image: url('https://picsum.photos/1200/400');
}
