i use jQuery validation plugins for my register form and everything looks fine except the span. If i put something meet the requirement the span will automatically change and this goes for every form except username (There is a error in php i think?!). 

this is my jsfiddle model.

And btw how can i remove the error label when the box is green. (When there is no error there is a white space)

my apology my english is not that great.

have a nice day
