Answer 1

Seems to me (from your code) that you are not closing the list_right tag. Close it and it should work properly... try to indent your code, make it look more clean, so that in the future you will be able to see the problems yourself.

Answer 2

You have <style> tags in your css in your original fiddle link which demonstrates the problem your were having.
Delete them, they shouldn't be there.
That's what's interfering with the list_right class.
