如何使第二列的第二行与第一列的高度相同

你好美洛

我正在尝试构建一个基本上看起来像这样的布局（蓝线是滚动条）布局图

但是现在我有了它，下面的绿色框超过了整个框的总高度。我将我创建的内容的粗略版本上载到了Codepen上，我使用的是Bulma框架，本质上我希望第二列的下部框是一个高度，其中左列的总高度等于右列的高度柱。

因此，我希望它在黑线处结束，并在右侧保持滚动条。

我可以将下部框的高度设置为特定的视图高度，这可以修复一点点，只是将溢出设置为滚动即可，但是如果您尝试调整其大小，它会有些混乱。

最糟糕的是，我可以通过使下框的高度等于的高度来使用JavaScript来做到这一点，left column - height of top box但我试图看看是否有更好的CSS方式。

我的解决方案：设置.column.is-2方向栏为flex，使用设置#getHeight display: block并使其底部滚动overflow: auto。Codepen演示：https：//codepen.io/anon/pen/ZVJdgj

html {
    overflow:hidden;
}

.fullh:not(:last-child) {
    margin-bottom: 0rem;
}

.fullh:last-child {
    margin-bottom: 0rem;
}

.fullh{
    margin-top: 0rem;
    margin-left: 0rem;
    margin-right: 0rem;
}

.shadow {
  box-shadow: 0 14px 28px rgba(0,0,0,0.25), 0 10px 10px rgba(0,0,0,0.22);
}

option:hover{
    background-color:#F1F6FE;
}

.is-vertical-center {
  display: flex;
  align-items: center;
}

.component-helper {
    cursor: pointer;
    color: #74A2F8;
}

.component-helper:hover {
    color: #504A77;
}

.column.is-2 {
    display: flex;
    flex-direction: column;
}

#getHeight {
  display: block;
}

.column.is-2 > .scroll {
  overflow: auto
}
