html - 删除 overflow-auto div 下的空白

Question

我添加了 css 属性“overflow: auto;”引导选项卡。它有效，但选项卡下方有一个空白区域。

知道我做错了什么吗？谢谢

我试过改变高度，切换到溢出隐藏，但没有成功。

工作示例: https://codepen.io/carlo-designer/full/WBrxra https://codepen.io/carlo-designer/pen/WBrxra

预期结果:页面底部没有空白

代码如下(请使用bootstrap 4.3)

.h-40 {height:40%;}		
.h-10 {height:10%;}
.h-50 {height:50%;}
.over {overflow:auto;}

Answer 1

用这个

.row div[class*="col-"]{
  height: 100%;
}

并添加 max-height:50vh; 而不是 height 50%;
