为什么我的 Bootstrap 5 个选项卡在单击时没有切换？

Question

我是新手，花了一些时间学习 HTML、CSS 和 Bootstrap (5)。作为练习这些技能的入门项目，我正在尝试复制另一个网站，其中包括（除其他外）一个选项卡式部分。

我按照教程创建了一个选项卡式部分，并获得了每个选项卡中的所有内容（每个选项卡中有两列 - 一列带有图片，一列带有 H3 和一些文本）。但是，当尝试在选项卡之间切换时，选项卡不会切换。

原来的教程非常简单，在它不起作用之后我尝试在这里和 Google 上搜索。其他一些人建议为每个 div 添加角色和 aria 控件，我尝试了但仍然没有成功。

请看一看，让我知道我错过了什么！

除 id 值外，您已正确完成所有操作。它不应该以数字开头。您可以在此处阅读更多相关信息 What are valid values for the id attribute in HTML?.
