我有以下使用 Bootstrap 的html。它在大多数情况下都能正常工作-但是关闭按钮没有出现在警报中。我在这里遗漏了什么代码？请注意，我是 Bootstrap 的新手-所以，它可能很简单。

您的代码中缺少此行。

<a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>

例如：

<div class="alert alert-success">
    <!-- you missed this line of code -->
      <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
      <strong>Success!</strong> Bootstrap applied to alert.
    </div>

祝你好运

您需要自己提供关闭按钮。如示例所示，请使用以下内容：

<div class="alert alert-warning alert-dismissible" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>

更新：2023 Bootstrap 5您可以只包含_close.scss文件， Bootstrap X将显示为SVG。
