Question

在主类中，有grid-template-rows: 1fr 1fr会将整个部分分成两半（sidebar和content类嵌套在该main类元素中）。但是，达到900像素后，它会留一个空白空间，并停留在该部分的顶部，而另一半留空。

我希望主体部分在达到某个断点后填满剩余空间，并且被卡住了。

这是一个很大的职位，这可能使我获得了第一次实习机会，所以如果有人帮助我找到解决方案，我将不胜感激！

在900px以上，除了grid-template-rows: 1fr 1fr导致的两行外，您还有两列。您可以通过添加定位到900px以上的grid-template-rows: auto来将其重置为单个列-请参见下面的演示

body {
  margin: 0;
  padding: 0;
  min-height: 100vh;
  box-sizing: border-box;
}

.header,
.footer {
  height: 100px;
  background-color: #1A1C22;
}

.sidebar {
  background-color: #6C757D;
}

.content__box {
  background-color: #343A40;
}

.content {
  display: grid;
  grid-gap: 15px;
}

.main {
  min-height: 400px;
  height: calc(100vh - 200px);
  display: grid;
  grid-template-rows: 1fr 1fr;
  grid-gap: 15px;
  padding: 15px 0;
}

@media (min-width: 600px) {
  .content {
    grid-template-columns: 1fr 1fr;
  }
}

@media (min-width: 900px) {
  .main { /* changed from 'main' to '.main' for specificity reasons */
    grid-template-rows: auto; /* added */
    grid-template-columns: 400px 1fr;
  }
}

@media (min-width: 1200px) {
  .content {
    grid-template-columns: 1fr 1fr 1fr;
  }
}
