I have a question about the CSS property height:100% in Internet Explorer.
height:100% does not work in IE, but it does in Firefox and Chro
In order to use height: 100%, the parent container should have a fixed height.
So for example while this should work:
Left Column
Right Column
The following will not work:
--- same code
One way to achieve a fixed height when you don't know parent's height is using position: absolute;.
Left Column
Right Column
Otherwise you could use javascript as noted in the other answer. But I prefer pure CSS solutions.
Check here for a live fiddle.
Hope that helps.
