css - 嵌套列内的 Bootstrap 行，响应高度

Question

我试图让灰色文本填充此列中剩余的可用空间，同时随着窗口大小(剩余的 100 像素左右)增大/缩小。灰色文本区域的底部应与左侧的大图像平齐。

我在想有一个 flexbox 解决方案，但似乎没有什么效果很好。

也许解决方案是从整个右列中删除 BS 类？并用更多的 css 编写这个部分？

Answer 1

试试这个，我确定这不是最好的代码，但这是我现在能想到的。

解决方法很简单:

• 使用 flexbox 使前两个列等高
• 然后在右栏中制作容器(其中包含 2 个小栏 - 我已经在此处修改了您的 html 结构，希望它不会按照您的意图出错)右栏的全高
• 在其中一个容器中添加背景
• 使 content-text 区域有顶部边框，使其看起来与 img 分开。

就这些，您可以在下面的代码中看得更清楚。希望对您有所帮助!

img {width:100%}
.content-box {background-color: gray}
.content-text {border-top:15px solid white;}
.row-eq-height {display: flex; flex-wrap: wrap}
.fullHeight {display: flex}
