Question

这是我的警报代码，它不起作用，我的意思是我在屏幕上看不到任何东西，一切似乎都很好，我认为没有我缺少的 javascript 函数，因为它只是一个文本

<div class="alert alert-success" role="alert">
        <h4 class="alert-heading">Well done!</h4>
        <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
        <hr>
        <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
      </div>

这些是我正在使用的脚本：

请发布完整的 HTML 文件。根据 Bootstrap documentation，您应该将该 CSS 链接放入 head 标记中。对于 Bootstrap alert styling，您不需要包含任何 JS 文件。它应该可以正常工作。
