如何修复 bootstrap 轮播错误？
How to fix bootstrap carousel bug?
旋转木马的最后一个项目没有正确显示并且破坏了旋转木马本身。但是当我注释掉轮播的第三项时，它看起来很好，没有任何东西，轮播中没有最后一项。我该如何修复这个错误？所有必要的东西都已链接，例如 bootstrap、jQuery 和 font-awesome。

首先将 carousel-indicators 、 carousel-control-prev 和 carousel-control-next 元素移到 carousel-inner div 元素之外。另外，您的 carousel-item div 之一未关闭。我对代码做了一些修改，请检查它现在是否有效
