Bootstrap Alert Size Change
提问by user2399308

这是我的警报示例：
<div class="alert alert-success">Your first number was correct.</div>

.alert {
width:300px;

I think it would work to just take the code from the question
我认为只从问题中获取代码就行了
<div class="alert alert-success">
and add one of the column classes like this
并添加这样的列类之一
<div class="alert alert-success col-md-3">
Something like that worked for me anyhow, my exact code was
无论如何，这样的事情对我有用，我的确切代码是
<div class="alert alert-info alert-dismissible col-md-3" role="alert">
Made a nice small alert out of it just a bit bigger than a button.
用它制作了一个不错的小警报，只是比按钮大一点。

If your alert is part of a .rowthen setting its class to include .col-lg-12will force it to span across its container.
如果您的警报是 a 的一部分，.row则将其类设置为 include.col-lg-12将强制它跨越其容器。
