我添加了css属性“ overflow：auto;”引导选项卡。 可以，但是选项卡下面有空白。
任何想法我在做什么错？谢谢
我试图更改高度，切换到隐藏的溢出状态，但是在那里没有成功。
工作示例： https://codepen.io/carlo-designer/full/WBrxra https://codepen.io/carlo-designer/pen/WBrxra
预期结果： 页面底部没有空格
下面的代码（请使用引导程序4.3）
.h-40 {height:40%;}
.h-10 {height:10%;}
.h-50 {height:50%;}

在弹性框中默认情况下，对齐项目：Stretch; 您只需要添加align-items：flex-start;
答案 1 :(得分：0)
使用此
.row div[class*="col-"]{
height: 100%;
}
并添加max-height:50vh;而不是50％的高度；
