I used the example here
Twitter bootstrap 3 two columns full height
I just added bootstrap.css in the file
http://jsfiddle.net/qhoc/scsGj/136/
http://netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css
If I run in jsfiddle, it's fine. But if I run outside of jsfiddle, it doesn't have full height any more. See: http://jsfiddle.net/m/jva/
Any suggestion on why is this the problem?
