如何使div高度填充可用空间

Question

我有一个3列布局,列下面有一些细节.

您会注意到其中一列的高度大于其他列的高度.我希望其他两个div自动填充剩余的空间(直到蓝色div).文本将动态加载,因此我需要使用它来处理任何更大的列(以及任意数量).

这可以用HTML/CSS完成,还是必须使用一些JavaScript？

        Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

CSS解决方案是使用背景颜色为外部容器设置样式,这称为假(虚假)bakcground.

像这样:

#iconsHolder {
    background-color: #DDD;
}

这种方法(至少在这种情况下)保证所有人的背景相同.
