Why can't this code be implemented: when the mouse is not clicked, it is blue, when it is clicked, it is yellow, then click the second one, the second one is yellow, and the previous one returns to blue? ? ?

I found that the main problem is 1.visited. Is there a problem here? 2. When you open this page, aren’t they all blue?


Reply to discussion (solution)

.link a:link{    color:blue;}a:visited{    color:yellow;}a:hover{    color:red;}a:active{    color:#ccc;}

Remove the previous .link

Also remove the first one , typo.

You separate this attribute a into different classes, and then set its attributes. For example:





  • css:
    .a a:link{}
    .b a:link{}
    .c a:link{}
    .d a:link{}
    You should get the effect you want
