Question

我是CSS网格的新手，我有一个嵌套的grid layout page。我无法获得网格儿童 div.fieldsContainer 的滚动条。

＆＃13;

html,body,
.wrapper{
  height: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

.wrapper{
  display: grid;
  grid-template-rows: 50px 1fr 50px;
}

.header{
  border: 1px solid #ddd;
  background: lightyellow;
}

.footer{
  background: lightpink;
}

.content{
  display: grid;
  grid-template-columns: 250px 1fr 300px;
  grid-gap: 10px;
  overflow: hidden;
}

.fieldTypes{
  display: grid;
  grid-template-rows: 40px 1fr;
}

.fieldTypes .search{
  border: 1px solid red;
}

.fieldTypes .fieldsContainer{
  display: grid;
  grid-template-columns: repeat(3, minmax(70px,1fr));
  grid-auto-rows: 50px;
  grid-gap: 10px;
}

.card{
  padding: 10px;

Answer 1

一种解决方案是在overflow-y:auto上的父.fieldTypes）和overflow-y:scroll上设置.fieldsContainer

这背后没有'故事'。只是你必须设置父接受它的默认溢出，然后在子节点上指定overflow-y：scroll（如你想要垂直滚动）。

html,body,
.wrapper{
  height: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

.wrapper{
  display: grid;
  grid-template-rows: 50px 1fr 50px;
}

.header{
  border: 1px solid #ddd;
  background: lightyellow;
}

.footer{
  background: lightpink;
}

.content{
  display: grid;
  grid-template-columns: 250px 1fr 300px;
  grid-gap: 10px;
  overflow: hidden;
}

.fieldTypes{
  display: grid;
  grid-template-rows: 40px 1fr;
  overflow-y:auto;/*added*/
}

.fieldTypes .search{
  border: 1px solid red;
}

.fieldTypes .fieldsContainer{
  display: grid;
  grid-template-columns: repeat(3, minmax(70px,1fr));
  grid-auto-rows: 50px;
  grid-gap: 10px;
  overflow-y:scroll;/*added*/
}

.card{
  padding: 10px;
  background: #ddd;
}

<div class="wrapper">
  <div class="header">
    Header
  </div>
  <div class="content">
    <div class="fieldTypes">
      <div class="search">search</div>
      <div class="fieldsContainer">
        <div class="card">1</div>
        <div class="card">2</div>
        <div class="card">3</div>
        <div class="card">4</div>
        <div class="card">5</div>
        <div class="card">6</div>
        <div class="card">7</div>
        <div class="card">8</div>
        <div class="card">9</div>
        <div class="card">10</div>
        <div class="card">11</div>
        <div class="card">12</div>
        <div class="card">10</div>
        <div class="card">11</div>
        <div class="card">12</div>
        <div class="card">10</div>
        <div class="card">11</div>
        <div class="card">12</div>
      </div>
    </div>
    <div class="inndercontent">
      innder content
    </div>
    <div class="graphs">
      graphs
    </div>
  </div>
  <div class="footer">
    Footer
  </div>
</div>

Answer 2

这里的案例要少得多（切掉不相关的部分）

html, body, .A {
  height: 100%; /* matters */
  width: 100%;
  margin: 0;
  padding: 0;
}

.A {
  max-height: 300px; /* matters */
  display: grid; /* matters */
  overflow: hidden; /* matters */
}

.B {
  display: grid; /* matters */
  overflow-y: auto; /* matters */
}

.D {
  overflow-y: scroll; /* matters */
}

.C {
  padding: 10px;
  background-color: #07f;
}

.E {
  padding: 10px;
  background-color: #eee;
}

<div class="A">
  <div class="B">
    <div class="C">search</div>
    <div class="D">
      <div class="E">1</div>
      <div class="E">2</div>
      <div class="E">3</div>
      <div class="E">4</div>
      <div class="E">5</div>
      <div class="E">6</div>
      <div class="E">7</div>
      <div class="E">8</div>
      <div class="E">9</div>
      <div class="E">10</div>
      <div class="E">11</div>
      <div class="E">12</div>
      <div class="E">10</div>
      <div class="E">11</div>
      <div class="E">12</div>
      <div class="E">10</div>
      <div class="E">11</div>
      <div class="E">12</div>
    </div>
  </div>
</div>

div中的垂直滚动条，是css网格列的子节点
