Bootstrap 4 Card Carousel 未显示多个项目

编程问答 2022-05-01

问题描述

关于错误 https://gifyu.com/image/5JCX

的 GIF 文件

卡片轮播代码取自 https://www.codeply.com/go/EIOtI7nkP8/bootstrap-carousel-with-multiple-cards

那个网站的CSS代码和JS代码是一样的。 CSS 文件已链接。 js文件最后是这样写的

<script type="text/javascript">
</script>

我在 Card Carousel 编辑器中使用的代码。

缺少脚本，您可以在最后运行此代码。
