引导3：仅在较小的屏幕尺寸上推/拉列

我在页面上有以下布局：

I have the following layout on a page:

<div class="col-lg-3">1</div>
<div class="col-lg-2">2</div>
<div class="col-lg-2">3</div>
<div class="col-lg-2">4</div>
<div class="col-lg-3">5</div>

 --------- ----- ----- ----- ---------
|    1    |  2  |  3  |  4  |    5    |
 --------- ----- ----- ----- ---------

但是在较小的屏幕尺寸上，我想要以下布局：

But on smaller screen sizes I would like the following layout:

<div class="col-xs-6">1</div>
<div class="col-xs-6">5</div>
<div class="col-xs-4">2</div>
<div class="col-xs-4">3</div>
<div class="col-xs-4">4</div>

 ----------------- -----------------
|        1        |        5        |
 ----------------- -----------------
|     2     |     3     |     4     |
 ----------- ----------- -----------

（请注意重新排列列顺序。）只能在较小的屏幕尺寸上推/拉列吗？我试过以下，但我得到最奇怪的布局，似乎失去了< div> 5< / div> 完全...：

(Note the re-arranging of the column order.) Is it possible to push/pull columns only on smaller screen sizes? I've tried the following, but I get the oddest layout, and seem to lose <div>5</div> completely...:

<div class="col-lg-3 col-xs-6">1</div>
<div class="col-lg-2 col-xs-4 col-xs-push-4">2</div>
<div class="col-lg-2 col-xs-4>3</div>
<div class="col-lg-2 col-xs-4>4</div>
<div class="col-lg-3 col-xs-6 col-xs-pull-12">5</div>
