Har*_*til 3 html css twitter-bootstrap

我试图在我的项目中实现引导程序..但是 col-md-3 占用了容器的整个宽度

以下是代码:-

避免使用内联width: 25%col-x-*类。同样为了支持移动宽度,添加col-xs-6.

col-xs-没有最低的屏幕尺寸,因此是很有意义总是包含它。这在这篇Boostrap Grid Sizes帖子中有进一步的解释。为了节省您的阅读时间,您感兴趣的主要部分是:

  • .col-xs-: 电话 (<768px)
  • .col-sm-: 平板电脑 (?768px)
  • .col-md-: 桌面 (?992px)
  • .col-lg-: 桌面 (?1200px)

要添加偏移量,请使用 col-md-offset-4
