Bootstrap - 仅在小型设备上有行

Question

对于我的计划页面,我使用的面板包含每个计划提供的内容.

我遇到的问题是因为每个面板的大小不同,当您在移动设备上查看时,它看起来像这样:

<div class="row">
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 1 --> </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 2 --> </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 3 --> </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 4 --> </div>
    </div>
</div>

我希望它看起来像这样:

<!-- This is how I attempted to do it -->
<div class="row">
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 1 --> </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 2 --> </div>
    </div>
</div>
<div class="row">
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 3 --> </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-md-3 col-lg-3">
        <div class="panel"> <!-- Panel 4 --> </div>
    </div>
</div>

但是,当我这样做时,它在大屏幕上看起来像这样:

如何在不重复我的代码并对行使用hidden-*和visible-*的情况下,如何实现2个小屏幕和4个大屏幕？

我通过将左侧两个div元素和右侧两个div元素分别放在各自的容器中来实现它.然后我使用了,和的组合col-lg,以达到你想要的效果:col-mdcol-sm

        <div class="letter-space">
            <div class="row">
              <div class="col-lg-6 col-md-12 col-sm-12">
                <div class="col-md-6 col-sm-12 col-nopadding padding-top padding-bottom text-center text-center">
                  <div class="panel panel-default">
