我在旋转木马中滚动效果时遇到问题。只是动画，简单的滚动工作，但动画没有。 也许有人可以检查我的代码并修复 ^_^ 谢谢。 图像在 class carousel-image-1(2,3) 的 css 中添加。我比较了官方 Bootstrap 站点上的示例以及我的代码中的所有示例。可能我没看出错误在哪里

您只需为 slider 指定高度 - 因为它默认为 0 像素高。 :-)
正如您在下面看到的，我刚刚添加了一个 400 像素的 min-height(您可以将其设置为任何您喜欢的值)，并且我还设置了一个随机背景，这样您就可以看到你的白色文本(因为它没有出现在你的例子中，但 slider 实际上在幕后工作。
.carousel-item {
min-height: 400px;
background-image: url('https://picsum.photos/1200/400');
