Question

我正在使用Bootstrap 4和php编写示例应用程序。我试图让两列在某个断点处彼此相邻显示。这是一个例子。我该怎么解决？

            <div class="col-lg-3" style="margin: 20px 0;">
                 <h4>Displaying ### results</h4>

Answer 1

关于Bootstrap要记住的最重要的事情是，每行必须的列数必须总计为12。与其将col-sm-6放在每个记录容器上，不如说是要做的是在其上放 row ，然后将col-6添加到PHP循环内输出的每个<div>记录元素中。

这可以在下面看到：

      </div>
      <div class="col-lg-3" style="margin: 20px 0;">
        <h4>Displaying ### results</h4>
      </div>
    </div>
    <div class="row">
      <div class="col-lg-3 col-sm-12">
        <p>Search field</p>
        <p>Search field</p>
        <p>Search field</p>
        <p>Search field</p>
      </div>
      <!-- at col-sm-6 I want two columns to display. how can i solve this? -->
      <div class="col-lg-9 row">
        <div class="col-6">
          Record
          <hr/>
        </div>
        <div class="col-6">

        <div class="col-6">

此外，请注意，col-6将适用于Bootstrap 4中的所有宽度，而col-sm-6仅适用于更大大于575px的宽度：

Answer 2

看来您的列数不匹配。

我怀疑这点...

<div class="col-lg-3 col-sm-12">

应该是...

<div class="col-lg-3 col-sm-6">
