正方形与flexbox的正方形

Question

我正在尝试使用flexbox重新创建以下布局：

我几乎有布局明智，但我得到一些奇怪的flex-wrap行为，如下所示：

我的css如下：

.parent {
    display: flex;
    justify-content: space-between;
    .square-container {
      width: calc(33% - 1.333px);
      display: flex;
      flex-wrap: wrap;
      justify-content: space-between;

    &:before {
      content:'';
      float:left;
      padding-top:100%;
      }

      .small-square {
          width: calc(50% - 2px);
          height: calc(50% - 2px);
          background: red;
          flex-shrink: 0;
      }     
    }
}

html如下：

<div class="parent">
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="large-square"></div>
</div>

我觉得我在这里错过了一些重要的flexbox属性。谢谢你的帮助！

你可以很容易地做到：

＆＃13;

＆＃13;

.flex {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  height: 210px;
  justify-content: space-between;
  width: 650px;
}

.small {
  width: 100px;
  height: 100px;
  background: red;
}

.large {
  width: 210px;
  height: 210px;
  background: red;
}

＆＃13;

<div class="flex">
  <div class="small"></div>
  <div class="small"></div>
  <div class="small"></div>
  <div class="small"></div>
  <div class="large"></div>
  <div class="small"></div>
  <div class="small"></div>
  <div class="small"></div>
  <div class="small"></div>
</div>

完全响应当前的html：

＆＃13;

＆＃13;

.parent {
  width: 100%;
  display: flex;
  flex-direction: row;
  justify-content: space-between;
}

.parent:after {
  content: '';
  display: block;
  width: 0;
  background: blue;
  padding-top: 33.3333%;
}

.square-container {
  width: calc(33.33333% - 5px);
  flex-grow: 1;
  display: flex;
  flex-wrap: wrap;
  flex-direction: row;
  justify-content: space-between;
}

.small-square {
  width: calc(50% - 5px);
  height: calc(50% - 10px);
  background: red;
}

.large-square {
  margin: 0 10px 10px 10px;
  flex-grow: 1;
  width: 33.33333%;
  background: red;
  order: 2;
}

.square-container:first-child {
  order: 1;
}

.square-container:nth-child(2n) {
  order: 3;
}

＆＃13;

<div class="parent">
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="large-square"></div>
</div>

Answer 2

无法更改HTML：

.parent {
  display: flex;
}

.square-container {
  flex: 1;
  display: flex;
  justify-content: space-around;
  align-content: space-between;
  flex-wrap: wrap;
}

.small-square {
  flex: 0 0 45%;
  height: 100px;
  background-color: red;
}

.large-square {
  flex: 1;
  height: 210px;
  margin: 0 5px;
  background-color: red;
}

.square-container:nth-child(2) {
  order: 1;
}

<div class="parent">
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="square-container">
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
    <div class="small-square"></div>
  </div>
  <div class="large-square"></div>
</div>
