Twitter bootstrap 引导中的stage和block类是什么？

我在Twitter引导程序中找不到两个类的描述：

stage

和

block

。这两个类的角色是什么

例如：

<div class="stage">
  <div class="block">
    <div class="container">
      <div class="row">
        Hello World!
      </div>
    </div>
  </div>
</div>

---

stage

和

block

不是引导类。它可能来自您自己的CSS，或者来自另一个库

---

这里有一个。据我所知，它是完整的。

我找到了它们。

他们在公园里。向下滚动右面板，查找新组件块和插件阶段

Mistalis，我刚刚编辑了将类阶段的定义包含在文件toolkit.js中。它是引导的一部分吗？它不是引导的一部分，它似乎是一个扩展引导的库，正如您在回答中所说的。查看我的链接以查看引导类的完整列表：）
