反向网格排列?

Reverse grid arrangment?

我右边有侧边栏,左边有内容:

<div class="col-md-9">
  <p>Main. At large zoom -- currently it goes to top. I want it to go to the bottom.</p>
</div>

<div class="col-md-3">
  <p>Sidebar. At large zoom -- currently it goes to bottom. I want it to go to the top.</p>
</div>

我希望侧边栏在放大时向上移动(例如 phone)。但是 bootstrap 将它发送到底部: http://www.bootply.com/nqOuCvbXZR

Bootstrap 3 个文档使用相同的布局并遇到相同的问题:例如参见 [​​=12=]

是否可以修改bootstrap默认排列规则?

首先考虑移动设备。将移动设备上的列放在第一位。并为更大的屏幕使用拉和推。

<div class="col-xs-12 col-md-push-9 col-md-3">
  <p>Sidebar. At large zoom -- currently it goes to bottom. I want it to go to the top.</p>
</div>

<div class="col-xs-12 col-md-pull-3 col-md-9">
  <p>Main. At large zoom -- currently it goes to top. I want it to go to the bottom.</p>
</div>
