Does a:link select the links that haven’t been visited yet？
I think the link should be green if it hasn’t been visited because I set a:link color to be green. But it obeys to the a:visited rule set. If a:visited color is black, the color of the link turns to be black. If a:visited color is blue, the color of the link turns to be blue. So I don’t know how a:link works.
Thank you for your reply.
