Hi all,

In fact, I see this animation here ,and I try to modify it where

the line animation for .progress span moves  vertically and the 

two div tags , div.left slides to left and div.right slides to right after the line animation complete.

here the code. where the output is nothing appear ,Although the height of the span

 Increased. and I get this error " Property '#<Object>' of object #<Object> is not a function ".

Thanks
