我第一次使用CSS 网格布局，它们很棒。然而，现在，我无法控制我的一个网格单元。

我想要的是有一个元素占用现有的可用空间而不是更多，当内容变得太大时滚动。我的理解是，在1fr计算完其他所有内容后，网格大小会占用统一数量的可用空间。我尝试了各种尺寸，例如minmax(auto, 1fr)但无济于事 -1fr似乎扩展以适应我不想要的内容。设置最大尺寸大小100px也不好，因为我希望大小由网格中的其他元素确定。

这是示例：

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

.container>div {
  border: 1px solid blue;
  border-radius: 5px;
}

.left {
  grid-column: 1;
  grid-row: 1/4;
}

.header {
  grid-column: 2;
  grid-row: 1;
}

.problem-child {
  grid-column: 2;
  grid-row: 2;
  overflow-y: scroll;
}

.footer {
  grid-column: 2;
  grid-row: 3;
}
<div class="container">
  <div class="left">left<br>I don't want this one to scroll<br>this should<br>determine<br>the height of the whole grid container</div>
  <div class="header">column header</div>
  <div class="problem-child">problem child:<br>I<br>want<br>this<br>to<br>scroll<br>rather<br>than<br>making<br>everything<br>tall</div>
  <div class="footer">column footer</div>
</div>

我可以使用什么网格声明（如果有）让“问题孩子”在溢出时滚动而不是扩展？

您可以使用max-height:100%;and 也min-height留下足够的高度来显示适当的滚动条。（firefox 可以，chrome 暂时不行）

.container {
  display: grid;
  grid-template-rows: auto minmax(1fr, 25vh) auto;
  grid-template-columns: 1fr 1fr;
}

.container>div {
  border: 1px solid blue;
  border-radius: 5px;
}

.left {
  grid-column: 1;
  grid-row: 1/4;
}

.header {
  grid-column: 2;
  grid-row: 1;
}

.problem-child {
  grid-column: 2;
  grid-row: 2;
  min-height:4em;
  max-height:100%;
  overflow-y: auto;
}

.footer {
  grid-column: 2;
  grid-row: 3;
}
<div class="container">
  <div class="left">left<br>I don't want this one to scroll<br>this should<br>determine<br>the height of the whole grid container</div>
  <div class="header">column header</div>
  <div class="problem-child">problem child:<br>I<br>want<br>this<br>to<br>scroll<br>rather<br>than<br>making<br>everything<br>tall</div>
  <div class="footer">column footer</div>
</div>

作为一种解决方法，您还可以使用额外的包装器absolute将其从流中取出并将其调整为行的高度：（两种情况都需要最小高度才能在需要时正确显示滚动条）

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

.container>div {
  border: 1px solid blue;
  border-radius: 5px;
}

.left {
  grid-column: 1;
  grid-row: 1/4;
}

.header {
  grid-column: 2;
  grid-row: 1;
}

.problem-child {
  grid-column: 2;
  grid-row: 2;
  position:relative;
  min-height:4em;
  }

.problem-child >div {
  position:absolute;
  top:0;
  left:0;
  right:0;
  max-height:100%;
  overflow:auto ;
}

.footer {
  grid-column: 2;
  grid-row: 3;
}
<div class="container">
  <div class="left">left<br>I don't want this one to scroll<br>this should<br>determine<br>the height of the whole grid container</div>
  <div class="header">column header</div>
  <div class="problem-child">
    <div>problem child:<br>I<br>want<br>this<br>to<br>scroll<br>rather<br>than<br>making<br>everything<br>tall</div>
  </div>
  <div class="footer">column footer</div>
</div>

在@G-Cyr 的解决方案之上添加。至少应该有一个绝对定位的元素max-height可以工作。将容器设置为绝对定位。

.container {
  display: grid;
  grid-template-rows: auto 1fr auto;
  grid-template-columns: 1fr 1fr;
  height: 100%;
  width: 100%;
  position: absolute;
}

.container>div {
  border: 1px solid blue;
  border-radius: 5px;
}

.left {
  grid-column: 1;
  grid-row: 1/4;
}

.header {
  grid-column: 2;
  grid-row: 1;
}

.problem-child {
  grid-column: 2;
  grid-row: 2;
  max-height: 100%;
  overflow-y: auto;
}

.footer {
  grid-column: 2;
  grid-row: 3;
}
<div class="container">
  <div class="left">left<br>I don't want this one to scroll<br>this should<br>determine<br>the height of the whole grid container</div>
  <div class="header">column header</div>
  <div class="problem-child">problem child:<br>I<br>want<br>this<br>to<br>scroll<br>rather<br>than<br>making<br>everything<br>tall</div>
  <div class="footer">column footer</div>
</div>

有一个更优雅的解决方案，它使用视口高度单位 (vh)。只需应用于100vh您的容器：

.container {
  display: grid;
  grid-template-rows: auto 1fr auto;
  grid-template-columns: 1fr 1fr;
  height: 100vh; /* <- does the trick */
}

.container>div {
  border: 1px solid blue;
  border-radius: 5px;
}

.left {
  grid-column: 1;
  grid-row: 1/4;
}

.header {
  grid-column: 2;
  grid-row: 1;
}

.problem-child {
  grid-column: 2;
  grid-row: 2;
  overflow-y: scroll;
}

.footer {
  grid-column: 2;
  grid-row: 3;
}

body {
  margin: 0; /* fixes stackoverflow's markup */
}
<div class="container">
  <div class="left">left<br>I don't want this one to scroll<br>this should<br>determine<br>the height of the whole grid container</div>

如果您在 中定义另一个网格problem-child，则它再次无法正确呈现。overflow: auto您必须将属性从任何父网格下推到子网格。检查给定的codepen：

body {
  height: 100vh;  
  display: grid;
  grid-template-rows: 30px 1fr 20px;
  margin: 0;
}
.header {
  background: green;
}
.footer {
  background: magenta;
}
.page {
  overflow: auto;
}
.container{
  height: 100%;
  display: grid;
  grid-template-rows: 30px 1fr 1fr 30px;
}

.fill-content {
  background: red;
  overflow: auto;
}

.fix-content {
  background: yellow;  
}

.large {
  background: blue;
  width: 100%;
  height: 150px;
}
<div class="header">Page HEader
</div>
<div class="page"> 
<div class="container">
  <div class="fix-content"></div>
  <div class="fill-content">
    <div class="large">fill content 1 by vertical space or scroll it (red layer is filled, blue makes it scrolling)</div>
  </div>
  <div class="fill-content">
    <div class="large">fill content 2 by vertical space or scroll it (red layer is filled, blue makes it scrolling)</div>
  </div>
  <div class="fix-content"></div>
</div>
</div>
<div class="footer">Page Footer</div>
