与嵌套的 flexbox 网格作斗争

Question

我尝试使用基于负边距的网格系统 (susy) 实现类似网格的模式，但失败了。

我尝试使用 flexbox，但我不确定它是否真的可行，我认为最好的方法是 2 列（A 侧和 B 侧）并为框 (1) 提供 50% 的框 2 的 flex 高度，但它似乎不起作用。

据我所知，这是可行的。

.block {
  width: 100%;
  background: grey
}

.column {
    align-content: stretch;
    display: flex;
    flex-flow: column wrap;
    width: 50%;
}

.box_long {
  background-color: pink;
  flex: 0 0 50%;
  padding: 20px;
  border: solid 1px black;
}

.box_small {
  background-color: blue;
  flex: 0 0 25%;
  padding: 20px;
  border: solid 1px black;
}

.box_big {
  background-color: green;
  flex: 0 0 100%;
  padding: 20px;
  border: solid 1px black;
}

<div class="block">
  
  <div class="column">
    <div class="box_long">
    </div>
    <div class="box_big">
    </div>
  </div>

  <div class="column">
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_long">
    </div>
  </div>
  
</div>

这是你要找的吗？

* {
  box-sizing: border-box
}

.block {
  background: grey;
  display: flex;
  height: 250px;
}

.column {
  flex: 1;
  display: flex;
  flex-wrap: wrap;
}

.column.col {
  flex-direction: column;
  flex-wrap: nowrap;
}

.column.col div {
  flex: 1;
  border: 1px solid black;
}

.column.row div {
  border: 1px solid black;
  flex-basis: 50%;
  height: 25%;
}

.column.row .box_long {
  height: 50%;
  flex-basis: 100%;
}

.box_long {
  background-color: pink;
}

.box_small {
  background-color: blue;
}

.box_big {
  background-color: green;
}

<div class="block">

  <div class="column col">
    <div class="box_long">
    </div>
    <div class="box_big">
    </div>
  </div>

  <div class="column row">
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_small">
    </div>
    <div class="box_long">
    </div>
  </div>

Answer 2

这是一种可能适合您的方法：

（不更改 HTML。）

.block {
  display: flex;
  height: 100vh;
  background: grey;
}

.column {
  display: flex;
  flex-wrap: wrap;
  width: 50%;
}

.box_big {
  flex-basis: 100%;
  height: 70%;
  background-color: chartreuse;
  border: solid 1px black;
}

.box_small {
  flex: 0 0 50%;
  height: 35%;
  background-color: aqua;
  border: solid 1px black;
}

.box_long {
  flex-basis: 100%;
  height: 30%;
  background-color: violet;
  border: solid 1px black;
}

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

<div class="block">
  <div class="column">
    <div class="box_long"></div>
    <div class="box_big"></div>
  </div>
  <div class="column">
    <div class="box_small"></div>
    <div class="box_small"></div>
    <div class="box_small"></div>
    <div class="box_small"></div>
    <div class="box_long"></div>
  </div>
</div>
