使用flexbox的全角和多列 [英] Fullwidth and multiple columns using flexbox

问题描述

我正在尝试在同一容器上创建具有全角和多列的flexbox行.

I'm trying to create a flexbox row with fullwidth and multiple columns on the same container.

我已经尝试过flex-break: after;，但是不确定我缺少什么.我试图避免像.fullwidth和.multiple-columns这样的多个类.

I've tried flex-break: after; but am not sure what I am missing. I am trying to avoid having multiple classes like .fullwidth and .multiple-columns.

这是我要实现的目标:

------------------------
|                      |
|                      |
|       item A         |
|                      |
|                      |
------------------------
|          |           |
|          |           |
|     B    |      C    |
|          |           |
|          |           |
------------------------
|                      |
|                      |
|       item D         |
|                      |
|                      |

.collage {

推荐答案

您需要在flex容器上设置flex-wrap: wrap，然后在全角项目上设置flex: 0 0 100%，在半角项目上设置flex: 0 0 50%.另外，您还应该添加box-sizing: border-box.

You need to set flex-wrap: wrap on flex container, and then flex: 0 0 100% on full-width items and flex: 0 0 50% on half-width items. Also you should add box-sizing: border-box.

* {
  box-sizing: border-box;
}
.collage {
  display: flex;
  flex-wrap: wrap;
}
.collage-item {
  border: 1px solid black;
  flex: 0 0 50%;
  padding: 10px;
}
.fullwidth {
  flex: 0 0 100%;
}

<div class="collage">
  <!-- fullwidth -->
  <div class="collage-item fullwidth">a</div>

  <!-- two columns -->
  <div class="collage-item">b</div>
  <div class="collage-item">c</div>

  <!-- fullwidth -->
  <div class="collage-item fullwidth">d</div>
</div>
