Flexbox 网格 - 等高列

Question

我正在使用 Flexbox Grid (http://flexboxgrid.com/) 并且我试图使我的列高度相等而不是具有单独的高度。有谁知道如何做到这一点，因为我似乎无法在文档中找到任何相关内容。

<div class="container-fluid">
  <div class="row middle-xs">
    <div class="col-sm-6">
      <div class="motability-bg">
        <img src="/img/new-car-template/motab-bg.jpg" alt="motability seat">
      </div>
    </div>
    <div class="col-sm-6">
      <div class="motability-content-bg"></div>
      <div class="motability-content">
        <h1>Motability</h1>
        <p>Hello</p>
      </div>
    </div>
  </div>
</div>

目前我带有 img 标签的专栏比我的内容栏大。知道如何让它们相等吗？

谢谢，尼克

Answer 1

不要使用classmiddle-xs旁排

.middle-xs {
  -webkit-box-align: center;
  -webkit-align-items: center;
  -ms-flex-align: center;
  align-items: center
}
