我们在一个网站上做了，我们做的是把网格放在垂直的行。

We did this on a site, and what we did was put the grid in vertical rows.

示例：

<div class="row">
  <div class="col-lg-4">
    <div class="box"></div>
    <div class="box"></div>
    <div class="box"></div>
  </div>
  <div class="col-lg-4">
    <div class="box"></div>
    <div class="box"></div>
    <div class="box"></div>
  </div>
  <div class="col-lg-4">
    <div class="box"></div>
    <div class="box"></div>
    <div class="box"></div>
  </div>
<div>
