CSS pseudo-class selector: Add styles to hyperlinks (add styles to different states of the link)
A hyperlink has four Status:
Normal status (:link): The mouse is not placed on the previous link style.
Hover state (:hover): The style when the mouse is placed on the link.
Activate state (:active): Hold down the left mouse button without releasing it. This state is particularly short-lived.
Visited state (:visited): Press the left mouse button and pop it up, the style effect at this time.
In daily work, the following writing methods are used to add different styles to links:
a:link, a:visited{ color:#444; text-decoration: none; } //Combine "normal state" and "visited state" into one.
a:hover{ color:#990000; text-decoration:underline; } //"Mouse over" to create a single effect
