我第一次与CSS Grid Layouts合作，他们非常棒。但是，现在，我无法控制我的一个网格单元。
我想要的是拥有一个占用现有可用空间的元素而不再，当内容变得太大时滚动。我的理解是，在计算完所有其他内容后，网格大小minmax(auto, 1fr)会占用可用空间的统一数量。我尝试了各种尺寸，例如1fr，但无济于事 - 100px似乎扩展到适合我不想要的内容。设置像.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;
}这样的最大大小也不行，因为我希望大小由网格中的其他元素决定。
以下是例子：
<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><script>
var name1="value1";var name2="value2";var name3="value3";
</script>
我可以使用什么网格声明（如果有的话）来解决问题儿童的问题。滚动溢出而不是扩展？

您可以使用max-height:100%;和min-height留出足够的高度来显示正确的滚动条。 （firefox会这样做，Chrome目前不会）
.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absolute位置的额外包装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正确显示需要时滚动条
.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>

添加@ G-Cyr的解决方案。应该至少有一个元素绝对定位max-height才能工作。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>

还有一个更优雅的解决方案，它使用视口高度单位（vh）。只需将100vh应用于您的容器：
.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>
<div class="header">column header</div>

如果您在problem-child内定义了另一个网格，那么将再次无法正确显示它。
您必须将overflow: auto属性从任何父网格下推到子网格。
检查给定的代码笔：
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 class="fix-content"></div>
