Bootstrap 轮播照片列表不工作

Question

我目前正在尝试向我正在为某人制作的网站添加一个 bootstrap 轮播，每次我添加照片或标题时，照片要么在列表中排列，要么字幕堆叠在一起。有人可以帮忙吗？

网站是这样的：

堆叠在一起的照片：

带有 <h3> 和 <h4> 字符串的标题看起来像什么：

这是一小段代码（我使用了 bootstrap 在他们网站上的模板）：

Answer 1

不允许将 Bootstrap 列直接嵌套在其他 Bootstrap 列中。

Bootstrap 列必须始终有一个 Bootstrap row 作为父级。

参考：

https://getbootstrap.com/docs/4.0/layout/grid/#nesting

https://getbootstrap.com/docs/4.0/components/carousel/#with-captions

此外，Bootstrap 4.

中没有字形

Answer 2

在 bootstrap 4 每张幻灯片都应该有一个 class carousel-item 而不是 item 作为 bootstrap 3 ,

也因为@WebDevbooster mentiened boostrap 4 不包括字体 awsome 所以你控制使用 carousel-control-prev 用于上一个控制和 carousel-control-next 用于下一个：

请参阅下面的工作片段：

.carousel-inner img {
      width: 100%;
      height: 100%;
  }
