bootstrap 4多个元素上一次崩溃

标签： css twitter-bootstrap bootstrap-4

我添加了bootstrap carousel并更改为显示多个项目，虽然我遇到了问题

当我点击下一个徽标时，一切正常，但是当我点击上一个徽标时，在修复之前会同时出现多个徽标，会发生什么？我该如何解决这个问题？

您的指标编号似乎有些混乱。另外，根据我的口味，你有一点定制的CSS。所以，我把它撕掉并使用了原生的Bootstrap类，比如mx-auto（margin horizo​​ntal auto）。

查看此代码段然后开始逐位添加您自己的自定义代码，直到您看到它中断的位置：
