你能用单行Flexbox布局创建类似CSS网格的模板吗？

Question

我可以用flexbox制作这个结构吗？

我在下面给出了一个带有网格的示例，但我想用 Flexbox 来制作它。

.container {
    display: grid;
    grid-template-columns: auto auto auto;
    gap: 10px;
}
.grid-item {
    background-color: aquamarine;
}
.small {
    height: 200px;
}
.big {
    grid-row: span 10;
}

<div class="container">
    <div class="grid-item small">Cell 1</div>
    <div class="grid-item small">Cell 2</div>
    <div class="grid-item big">Cell 3</div>
    <div class="grid-item small">Cell 4</div>
    <div class="grid-item small">Cell 5</div>
    <div class="grid-item small">Cell 6</div>
    <div class="grid-item small">Cell 7</div>
    <div class="grid-item small">Cell 8</div>
    <div class="grid-item small">Cell 9</div>
    <div class="grid-item small">Cell 10</div>
    <div class="grid-item small">Cell 11</div>
    <div class="grid-item small">Cell 12</div>
</div>

我想用 Flexbox 实现什么：

width: 100%;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: flex-start;

和

<div class="item">1</div>
<div class="item">2</div>
<div class="item big">3</div>
<div class="item">4</div>
<div class="item">5</div>
<div class="item">6</div>
<div class="item">7</div>

这很有挑战性，因为

1. 带有显示屏柔性
2. 排成一排

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.container {
  display: flex;
  flex-wrap: wrap;
  position: relative;
  gap: var(--gap);
  padding-right: 50%;
  --gap: 8px;
}

.grid-item {
  width: calc(50% - calc(var(--gap) / 2));
  display: grid;
  place-items: center;
  background-color: coral;
}

.small {
  height: 200px;
}

.big {
  position: absolute;
  inset: 0 0 0 auto;
  width: calc(50% - var(--gap));
}

<div class="container">
  <div class="grid-item small">Cell 1</div>
  <div class="grid-item small">Cell 2</div>
  <div class="grid-item big">Cell 3</div>
  <div class="grid-item small">Cell 4</div>
  <div class="grid-item small">Cell 5</div>
  <div class="grid-item small">Cell 6</div>
  <div class="grid-item small">Cell 7</div>
  <div class="grid-item small">Cell 8</div>
  <div class="grid-item small">Cell 9</div>
  <div class="grid-item small">Cell 10</div>
  <div class="grid-item small">Cell 11</div>
  <div class="grid-item small">Cell 12</div>
</div>

到目前为止我知道，这是使用 Flexbox 的唯一方法，因为它是一维的。

*{
    margin: 0;
    padding: 0;
}

.flex-container{
  display: flex;
  flex-wrap: wrap;
  gap: 10px;
}

.flex-inner-container {
  display: flex;
  flex-wrap: wrap;
  gap: 10px;
  flex: 1 0 calc(50% - 10px);
}   

.flex-inner-container .item {
  background-color: aquamarine;
  flex: 1 0 calc(50% - 10px);
  height: 200px;
}

.big {
    flex: 1 0 calc(50% - 10px);
    background-color: aquamarine;
}

<div class="flex-container">
    <div class="flex-inner-container">
        <div class="item">1</div>
        <div class="item">2</div>        
        <div class="item">4</div>
        <div class="item">5</div>
        <div class="item">6</div>
        <div class="item">7</div>
    </div>

    <div class="item big">3</div>
</div>
