I have a set of divs like
<div id="div2"></div> <div id="div3"></div>
The content of 2 and 3 can make it so their heights are different, but I want to make it so they are always the same. So if div3 is taller than div2, div2 should stretch to be as tall as div3.
I thought setting their heights to 100% would do the trick, since if div3 gets taller, then div1 must get taller making it so div2 is no longer at 100% height and would need to stretch back to 100%. But this doesn't work. How can I do this?
