css - 如何将子项的高度填充到另一侧并排的高度；

问题描述

我正在尝试用 css 和 html 做一些块，其中很少有固定高度，例如你看到的 200px，但其他块需要动态/灵活，并且需要被其他高度拉伸。C、G、H 块需要是动态的，并且通过相对的块最大当前高度与内容拉伸。在图片中，您看到块超出区域，C、G、H 块需要在绘制红线的高度；

解决方案

你看起来像这样吗？

.mainContentSection {
  margin-top: 10px;
  color: white;
  display: flex;
  overflow: hidden;   /* I added this value*/
}

这是完整的代码。我还在 G 部分添加了一些文本以使其清楚。

.clearFix {
  clear: both;
}


/*        Header blocks    */

.headerBlockSection {
  color: white;
  font-size: 50px;
}

.block-A {
  width: calc((100% / 4 * 3) - 10px);
  height: 200px;
  background-color: #008000;
  float: left;
  margin-right: 10px;
}

.block-B {
  width: calc(100% / 4 * 1);
  height: 200px;
  background-color: #008000;
  float: left;
}

.contentSection-1 {

.contentSection-2 {
