像 Bootstrap 3 这样的 Bootstrap 4 Columns 浮动样式是否可能？

Question

我开始使用 bootstrap 4 进行开发，现在我发现了这个问题： 当使用 bootstrap 3 列系统时，因为它使用浮点数，我们可以在一行中插入多列，它会根据指定的“col-size”填充空间，如下所示：

http://codepen.io/seltix/pen/QpXvRJ

 -------   -------   -------
| COL 1 | | COL 2 | | COL 3 |
|       |  -------   -------
|       | | COL 4 | | COL 5 |
 -------   -------   -------

<div class="container-fluid">
  <div class="row">
    <div class="col-sm-6 panel height-1">
      <div class="bg-danger">this box is a slider with fixed col-6 width and fixes 2 blue boxes height</div>
    </div>
    <div class="col-sm-3 panel height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 panel height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 panel height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 panel height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 panel height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
</div>

但是使用 bootstrap 4 flex 系统，每个元素都使用行的全高，结果是这样的：

 -------   -------   -------
| COL 1 | | COL 2 | | COL 3 |
|       |  -------   -------
|       |
 -------   -------
| COL 4 | | COL 5 |
 -------   -------

<div class="container-fluid">
  <div class="row">
    <div class="col-sm-6 card height-1">
      <div class="bg-danger">this box is a slider with fixed col-6 width and fixes 2 blue boxes height</div>
    </div>
    <div class="col-sm-3 card height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 card height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 card height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 card height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
    <div class="col-sm-3 card height-2">
      <div class="bg-info">blue boxes count may change depending on the content.<br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
    </div>
</div>

我已经用谷歌搜索并在 bootstrap 4 文档中搜索，但我没有找到任何解决方案。我发现最接近的是卡片列，一个类似砖石的例子，但我认为它不适用于这个例子，因为我无法指定列/卡片的宽度。 谢谢！

是的，您可以使用实用程序类在 Bootstrap 4 中获得 3.x 网格“浮动”行为。

使用d-block 将行从 display:flex 更改为 display:block。然后在每个列上使用float-left..

 <div class="row d-block">
        <div class="col-md-6 float-left card height-1">
            <div class="bg-danger">1
                <br>this box is a slider with fixed col-6 width and fixes 2 blue boxes height</div>
        </div>
        <div class="col-md-3 float-left card height-2">
            <div class="bg-info">2
                <br>blue boxes count may change depending on the content.
                <br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
        </div>
        <div class="col-md-3 float-left card height-2">
            <div class="bg-info">3
                <br>blue boxes count may change depending on the content.
                <br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
        </div>
        <div class="col-md-3 float-left card height-2">
            <div class="bg-info">4
                <br>blue boxes count may change depending on the content.
                <br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
        </div>
        <div class="col-md-3 float-left card height-2">
            <div class="bg-info">5
                <br>blue boxes count may change depending on the content.
                <br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
        </div>
        <div class="col-md-3 float-left card height-2">
            <div class="bg-info">6
                <br>blue boxes count may change depending on the content.
                <br>if there are only 1 blue box the col size will change from 3 to 6 in the PHP</div>
        </div>
    </div>
