弹性物品的等高儿童

Question

我在创建一个flexbox响应网格时遇到了问题,并希望有人可以指出我正确的方向.

我希望所有的.blockdiv都是相同的高度,并且.bottomdiv绝对位于底部.这实际上是在当前的解决方案中工作,但是当h2标题太长并且达到2 h2行时,我希望行的所有标题都是相同的高度.

这有可能吗？

我做了一个Codepen来说明问题:http://codepen.io/kenvdbroek/pen/eZKdEQ

Answer 1

一般来说,这对于flexbox或CSS是不可能的.

Flex容器的初始设置是align-items: stretch.这会导致弹性项目扩展横轴的整个长度.这就是所谓的"弹性等高柱".

以下是一些要记住的注意事项:

• 等高列仅适用于儿童的柔性容器.换句话说,flex项必须具有相同的父项.否则,等高特征不适用.

  你的问题:

  我希望行的所有h2标题都是相同的高度.这有可能吗？

  没有CSS.因为h2它们存在于不同的容器中,它们不是兄弟姐妹(它们更像堂兄弟),所以平等的高度不适用.

• flexbox中的等高柱仅适用于一条柔性线.通过包装创建的其他线上的项目建立自己的相等高度线.这意味着相等高度的列不适用于多行Flex容器.

• 该align-self属性可用于覆盖单个弹性项目align-items,这可能会破坏相等的高度特征.

• 通过在柔性物品(例如,指定的高度height: 300px),两者都align-items和align-self被覆盖该项目,并且等于高度设置被忽略.

• 这篇文章的重点是一个容器flex-direction: row.如果容器是 flex-direction: column,则相等的高度变为相等的宽度.这是一个详细的评论:使flex项目占用内容宽度,而不是父容器的宽度
