如何使两列布局具有等高的列和一个可滚动的列？

Question

我想使用 CSS 网格在两列中显示两个区域。但是，左列的高度必须与右列的高度相同。

如果左列高于右列，则左列中的内容应该是可滚动的。

我想要实现的目标：

如果没有以像素为单位的硬编码高度，我就无法做到这一点。仅通过 CSS 可以做到这一点吗？或者我需要使用 JavaScript 重新计算左列高度？

我附上jsFiddle来看看。

由于宽度已知，您可以考虑position:absolute内容，因此它不会影响高度，只需使用top:0;bottom:0;

.gridwrapper {
  display: grid;
  grid-template-columns: 0.5fr 1.5fr;
  grid-auto-rows: 200px;
  grid-gap: 10px;
  grid-template-rows: auto;
}

.column {
  background: green;
  position:relative;
}

.dynamic-content {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 300px;
  background: pink;
  margin: 20px;
}

.list {
  position:absolute;
  overflow-y: auto;
  margin: 20px;
  top:0;
  bottom:0;
  left:0;
  right:0;
}

.item {
  height: 50px;
  background: yellow;
  border: 2px solid black;
}

<div class="gridwrapper">
      <div class="column">
        <div class="list">
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
          <div class="item"></div>
        </div>
  </div>
  <div class="column">
    <div class="dynamic-content">Some dynamic content with random height</div>
  </div>
</div>
