What is the difference between id and class on CSS?

I know that the major difference between id and class is that id can be used once per page but classes can be used as many times on a page as needed. Please clearify this statement and this question. ­čśŐ

You mistly have the differences stated in your question. If I want a .red class that simply assigns the color #FF0000 to whatever it's associated with, then that's fine; however, it's not good practice to do that with IDs. Think of a class as more general, while the ID is more specific.

Got it. Thanks @Mario L. An id is unique. It refers to one element. It may occure only once in the document. Classes define several related elements. If a class is addressed (e.g. by CSS or JavaScript) all elements belonging to that class are affected.
