I am looking for the easiest way to get a < ul > and it's < li > elements to a 100% height of the < ul >'s parent. The parent is not fixed (and I am trying to avoid that so it is flexible on mobile devices). Here is the JSFiddle
Basically I want the red boxes to be 100% height of the grayish box.
Thanks!
Note: I have tried various things already, its just nothing seemed to work properly.
