我怎样才能让每个折叠按钮单独工作?

how can I make every collapse button work separately?

我正在尝试设计一个在卡片组中包含 3 张卡片的博客,然后我在每张卡片的底部添加了折叠按钮,但问题是当我按下任何按钮时,它们会全部按下并显示第一个折叠按钮按钮的文本,即使我添加了 bootstrap css link 和 javascript 两个 links,我正在使用 bootstrap 这是我的代码正文,有什么建议吗?

您对两者使用了相同的 ID 选择器,这就是为什么单击一个按钮会影响另一个按钮的原因,要解决此问题,请使用单独的 #id 选择器, 请参阅下面的解决方案:
