html – Bootstrap 3.2：如何使3列包含另一个div相同高度的文本

使用Bootstrap 3.2,我有一个网站的一部分有三个div(.col-lg-3框),其中包含不同数量的文本.我希望他们都延伸到包含div(.row)的底部.我正在使用的CSS文件的链接在这里： https://github.com/ttmjason/GazoomTravel/blob/master/css/bootstrap.css.

我在Stack Exchange上看到的这个一般性问题(容器中相同的高度div)的答案要么不使用Bootstrap,要么具有过时的语法.如果你能把我链接到一个完全反映我的SxE问题,我很乐意接受这些问题来换取答案.
