Hi,
I am designing a portal where users can give rating.Now I want the user should give the rating on star,i.e. on a 5 star basis;5 star means excellent,4 star means very good and so on.
Now, if he selects 3 star,the remaining 2 stars should be of diff color[may be white]and the selected stars should be of yellow.
Can you give me any idea how to do it?If you can provide any useful link that will also do.
Thanks in advance.
