CSS Grid - 自动高度行，调整为内容

我有两个嵌套在网格中的网格。不幸的是，右侧嵌套网格.grid-3设置行的高度，以便左右网格都具有相同的高度，额外空间在具有类.right的div之间共享。如何设置右嵌套网格的行以调整内容的大小，因此它们与左嵌套行的高度相同？

div {
  border: 1px dotted black;
}
.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-auto-rows auto;
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-auto-rows auto;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}

您可以尝试minmax(min-content, max-content) ref 

div {
  border: 1px dotted black;
}
.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-auto-rows: minmax(min-content, max-content);
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-auto-rows: minmax(min-content, max-content);
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
<div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>

默认情况下，网格项会拉伸到所有网格单元区域。因此，如果您希望网格的高度适合内容，那么您可以在此处选择此选项：

  • 使用align-items为网格容器设置所有项目的对齐方式（默认值为align-items: stretch）。所以只需为align-items: start设置grid-2即可。演示：

    div {
  border: 1px dotted black;
}

.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  align-items: start;
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
    <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

  • 使用align-self（默认值为align-self: stretch）单独设置网格项的对齐方式。所以只需为align-self: start设置grid-3即可。演示：

    div {
  border: 1px dotted black;
}

.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  align-self: start;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
    <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>

        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

  • 使用带有margin值的auto属性单独设置网格项的对齐方式。网格单元的自动边距占用任何方向的所有可用空间。所以只需为margin-bottom: auto设置grid-3即可。演示：

    div {
  border: 1px dotted black;
}

.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  margin-bottom: auto;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
    <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

如果您希望右网格占据所有父级垂直空间但使其单元格适合内容使用this answer。

答案 2 :(得分：7)

您也可以尝试grid-auto-rows: fit-content(1em);。当然，请使用对您有意义的任何尺寸。我也尝试过 Temani（minmax(min-content, max-content)）和渲染HTML时的结果相同。

根据Elad Schechter - Medium

fit-content函数接受一个参数，即最大值。 ... fit-content（）函数类似于使用minmax（）函数，最小值为0。一个主要区别：min-max（）更有可能占用允许的最大空间，而fit-content不会占用多余的空间。

您的需求将确定fit-content是否比使用minmax更合适，反之亦然。
