假设我在一个包装器中并排有2个div。

Let's say I have 2 divs within a wrapper side by side.

<div id="wrapper"> <div id="primary"></div> <div id="secondary"></div> </div> #primary { width:50%; float: left; } #secondary { width: 50%; }

我如何确保div secondary始终与div primary具有相同的高度

How can I make sure div secondary always has the same height as div primary

推荐答案

不幸的是，如果不使用Javascript，则没有完美的方法来执行此操作，因为实际上两个div彼此都不了解。

Unfortunately there is no perfect method to do this without using Javascript as realistically the two divs know nothing about one another.
