css - Flexbox:如何在列上组合百分比、像素和剩余高度？

Question

我正在构建基本的网格系统，需要组合以不同大小单位(%、px 和剩余空间)描述的 flex 元素的高度。

html:

<div class="grid">
  <div class="block" style="flex-basis: 50px;">50px</div>
  <div class="block" style="flex-basis: 25%;">25%</div>
  <div class="block">stretch to remaining space?</div>
  <div class="block" style="flex-basis: 50px;">50px</div>
</div>

CSS:

html,body,.grid {
  height: 100%;
  padding: 0;
  margin: 0;
}
.grid {
  width: 300px;
  background: #aaa;
  display: flex;
  flex-direction: column;
  justify-content: flex-start;

}
.block {
  outline: solid 1px black;
  flex-grow: 0; // remove growing proportion
  flex-shrink: 0; // remove shrinking proportion
}

Answer 1

使用 flex-grow 参数(flex 简写属性中的第一个):

HTML:

<div class="grid">
  <div class="block a">block height 50px</div>
  <div class="block b">block height 25%</div>
  <div class="block c">block height *</div>
  <div class="block d">block height 50px</div>
</div>

CSS:

.block {
  outline: solid 1px black;
}
.a, .d {
  flex: 0 0 50px;
}
.b {
  flex: 0 0 25%;
}
.c {
  flex: 1 0 0;
}
