Question

我正在尝试将Carousel Bootstrap 4实施到个人项目中。我对HTML5，CSS3，Bootstrap 4和JS有基本的了解。我已经看了几个关于如何使用轮播组件的讨论和教程，但无法在浏览器中获得正确的输出。我使用chrome和firefox，并且在两个浏览器中都有同样的问题。我已经检查了（链接）和（脚本）的路径，我甚至不得不将（img data-src =“＃”）更改为（img src =“＃”），以便图像可以正确加载到浏览器中。图像相互叠加，不知道如何解决这个问题。我直接从Bootstrap网站复制代码。这是我第一次参加社区活动和第一个问题。只是对这个组件感到有点沮丧。

提前致谢！
