Summary

Online Bookworms |Daniel Palmer is a content manager of Online Bookworms, a website dedicated to lovers of books and reading. One of Daniels tasks is to create a comments page in which users can enter short comments in a text area box about books they have read. To keep the comments short and to the point, Daniel wants to limit each comment to 1000 words. He asks you to write a script that will update a character counter that shows the user how much of the 1000 characters has already been typed.

Daniel also wants users to be able to rate the books by moving a mouse pointer over a row of five stars. If the user moves the mouse pointer over the third star, the first three stars should be lit. If the user moves the mouse pointer over the fourth star, the first four stars should be lit and so forth. Clicking a star image enters that rating into an input box for processing.
