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）
但是按照我现在的方式，较低的绿色框超过了整个框的总高度。我已将我创建的内容的粗略版本上传到codepen，我使用的是 Bulma 框架，基本上我希望第二列中的下框的高度是左列的总高度等于右栏。
所以我希望它在黑线所在的位置结束，并在右侧有一个滚动条。
我可以将下框的高度设置为特定的视图高度，它可以稍微修复它，只需将溢出设置为滚动，但如果你尝试调整大小，它会有点混乱。
在最坏的情况下，我可以使用 JavaScript 来做到这一点，方法是使下框的高度等于 left column - height of top box 的高度，但我正在尝试看看是否有更好的 CSS 方式。

标签： javascript html css bulma
我的解决方案：将.column.is-2 设置为与方向列一起弯曲，设置#getHeight display: block 并使用overflow: auto 使底部一个可滚动。

margin-bottom: 0px; 添加到.column.is-2 > .scroll，在codepen 上更新：codepen.io/anon/pen/ZVJdgj
