The normal sequence is as follows:
a:link{text-decoration:none; color:#666;}
a:visited {text-decoration:none ; color:#666 ;}
a:hover {text-decoration:underline; color:#000;}
a:active {text-decoration:none ; color:#000 ;}
Yesterday when I was about to get off work, I wrote a hyperlink style, but it was always wrong. Before I clicked it, the mouse would turn black when I put it on it, but after I clicked it, When I put the mouse on this link again, there is no response, which is really a headache. .
I came to work this morning and just put a:hover after a:visited and try again. Hey~~I lost a lot of brain cells for this~~
