Question

我试图在单击按钮时打开Bootstrap模式，它会打开，但包含模态的整个屏幕变暗，我无法点击它上面的任何按钮。知道我做错了什么吗？我正在使用Bootstrap 4 beta 2

Answer 1

将您的模态代码移动到导航标记之外，如下所示。老实说，我不是百分之百确定原因，但我之前遇到过这个问题

不要更改任何bootstrap css，因为它很可能在将来出现问题。只需将代码移动一行即可。

Answer 2

.modal-backdrop.show{
  z-index:1;
}

这将把模态带到最顶层。

.modal-backdrop.show {
  z-index: 1;
}
