flexbox嵌套：两个垂直框中的两个垂直框，带有断点

Question

我想在一行中4 flex个框具有相同的高度。 有一个断点，4个弹性盒应该在两行中有两个弹性盒。现在每行中的2个Flexbox应该具有相同的高度。

以下是代码：

＆＃13;

＆＃13;

.content {
  color: #fff;
  font-size: 20px;
  margin: 50px auto;
  max-width: 1045px;
  padding: 0;
  text-shadow: 1px 1px #000;
}
.content .fullContainer,
.content .halfContainer,
.content .quarterContainer,
.content .quarterSecondContainer {
  display: flex;
}
@media (max-width: 1075px) {
  .content .halfContainer,
  .content .quarterSecondContainer {
    display: block;
  }
}
.content .fullContainer .full {
  background-color: #ff0;
  color: #000;
  margin-bottom: 15px;
  width: 1045px;
}
@media (max-width: 1075px) {
  .content .fullContainer .full {
    width: 515px;
  }
}
.content .halfContainer .half {
  background-color: green;
  margin-bottom: 15px;
  width: 515px;
}
.content .halfContainer .half:first-child {
  margin-right: 15px;
}
@media (max-width: 1075px) {
  .content .halfContainer .half {
    display: block;
  }
  .content .halfContainer .half:first-child {
    margin-right: 0;
  }
}
.content .quarterContainer .quarter {
  background-color: pink;
  color: #fff;
  margin-bottom: 15px;
  margin-left: 15px;
  width: 250px;
}
.content .quarterContainer .first {
  margin-left: 0;
}
@media (max-width: 1075px) {
  .content .quarterContainer .firstInSecond {
    margin-left: 0;
  }
}
