我有一个 SCSS，它使用网格来设计我的页面。请注意垂直滚动条。

现在，我想在这个表格的右侧再添加一个div。所以我在这个div后面添加一个div，并将display:grid添加到这两个div的容器中。结果，这些滚动条消失了，因为它们的 div 高度被搞乱了。

请取消 SCSS 中第 9-11 行的注释。

display: grid;
grid-template-columns: 1fr 1fr;
grid-gap: 10px;

那里发生了什么？

Answer 1

该行为可能与隐式创建的网格行中auto关键字的计算结果相关。

auto^ref

Is a keyword that is identical to maximal content if it's a maximum. As a minimum it represents the largest minimum size (as specified by min-width/min-height) of the grid items occupying the grid track.

例如，当grid-auto-rows(或grid-template-rows)属性设置为100%时，它看起来如下所示，问题已解决:

.component-container {
  width: 800px;
  height: 200px;
  background-color: lightyellow;
  border: 1px solid red;
  padding: 10px;
  overflow: hidden;
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-gap: 10px;
  grid-auto-rows: 100%;
}

.component-container {
  width: 800px;
  height: 200px;
  background-color: lightyellow;
  border: 1px solid red;
  padding: 10px;
  overflow: hidden;
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-gap: 10px;
  grid-auto-rows: 100%;
}

.component-container .grid-container-1 {
  display: grid;
  grid-template-columns: 150px 1fr 1fr;
  grid-template-rows: 50px 1fr 50px;
  grid-gap: 3px;
  padding: 3px;
  height: 100%;
  width: 100%;
  background-color: #2196F3;
}

.component-container .grid-container-1 .grid-item {
  background-color: rgba(255, 255, 255, 0.8);
  border: 1px solid darkblue;
  overflow: auto;
