引导程序4列未达到100%高度

bootstrap-4 css html

Pedz · 技术社区 · 6 年前

我正在使用bootstrap 4,我注意到我的列没有达到行的100%高度。

我假设bootstrap 4的一个特性是列高度始终与行高度相同,如本工作示例所示: http://demo.tutorialzine.com/2016/11/boostrap-4-regular-vs-flex-grid/?5-column-height

不知什么原因,我似乎不能产生同样的结果。我试过使用:

行上的对齐项拉伸类
高度:柱上100%
flex:1,带显示:flex和flex方向:列

我想知道是否有人可以解释正确的设置方法,以确保引导4列达到行高的100%。

从我们的研究容器中取出高度。

.our-research__container {         
     border: 1px solid blue;
     flex: 1;
     display: flex;
     flex-direction: column;
}
