关键词：viewport、栅格布局、媒体查询（Media Queries）
一、关于栅格布局的说明：
1、基本图解
extra small devices phones 超小型设备手机
small devices tablets 小型设备平板电脑
medium devices desktops 中型设备台式机
large devices desktops 大型设备台式机
2、混用案例说明
如：
HTML代码：
<div class="col-xs-12 col-sm-9 col-md-6 col-lg-3">
</div>
当屏幕尺寸
小于 768px 的时候，用 col-xs-12 类对应的样式；
在 768px 到 992px 之间的时候，用 col-sm-9 类对应的样式；
在 992px 到 1200px 之间的时候，用 col-md-6 类对应的样式；
大于 1200px 的时候，用 col-lg-3 类对应的样式；
二、制作登录页面
效果：
代码：
<!DOCTYPE html>
