答
你缺少你这行代码。
<a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
如:
<div class="alert alert-success">
<!-- you missed this line of code -->
<a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
<strong>Success!</strong> Bootstrap applied to alert.
</div>
好运

你希望自己提供的关闭按钮。作为the examples,使用类似:
<div class="alert alert-warning alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">×</span></button>
<strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>
