Question

我是一名高中网页设计老师，目前正在教我的学生如何建立他们自己的网格框架。我正在使用浮动.col方法，因为它易于理解，并且从教导浮动和清除方面流畅。我接下来要转向flexbox。

我遇到了一个奇怪的问题。在中等大小的屏幕上，并且在该断点内只有一定的尺寸，网格似乎“突破”。最后一个.col下降到下一行。以下是显示该JS Fiddle的http://localhost:8080/的链接。

这是HTML

<!-- Link to Font Awesome v4 -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">

<!-- Section from page that is 'breaking' at certian md sizes -->
<section id="features">
  <div class="container">
    <div class="row">
      <div class="col-lg-3 col-md-6">
        <i class="fa fa-map-marker" aria-hidden="true"></i>
        <h2>Mark Locations</h2>
        <p>Mappy lets you save important locations like home, work, or even where you parked your car!</p>
      </div>
      <div class="col-lg-3 col-md-6">
        <i class="fa fa-map" aria-hidden="true"></i>
        <h2>View Full Maps</h2>
        <p>Mappy also lets your look at up-to-date maps of towns, cities, and even the globe! </p>
      </div>
      <div class="col-lg-3 col-md-6">
        <i class="fa fa-map-signs" aria-hidden="true"></i>
        <h2>Get Directions</h2>
        <p>Let Mappy guide you where you want to go! Simply enter an address or location and Mappy will find the best route</p>
      </div>
      <div class="col-lg-3 col-md-6">
        <i class="fa fa-car" aria-hidden="true"></i>
        <h2>Realtime Traffic</h2>
        <p>Mappy is connected to local traffic updates, so it can always provide the fastest route to avoid jams</p>
      </div>

    </div>
  </div>
</section>

和CSS

} /*end tablet*/

/*Col Styles For Desktops*/

    .col-lg-8 {width: 66.66%;}
    .col-lg-9 {width: 75%;}
    .col-lg-10 {width: 83.33%;}
    .col-lg-11 {width: 91.66%;}
    .col-lg-12 {width: 100%;}
} /*End Desktop*/

我需要构建一个类并添加到此类吗？或者是否有一些我可以改变的方式我建立cols以完全避免这种情况？我在Bootstrap 3之后对此进行了建模。

Answer 1

看起来这是来自Mark Locations＆＃39;复制到比其旁边的模块更多的行。

我能够通过在col声明中添加一个最小高度为220px的类来解决这个问题。

.icon-height {
   min-height: 220px;
}

<div class="col-lg-3 col-md-6 icon-height">
