How CSS Sets the hyperlink style

CSS Settings hyperlink styles are implemented by pseudo-classes

(1): Link: Sets the style sheet properties of the A object before it is accessed.

(2): visited: Sets a style sheet property whose link address has been accessed by an object that is outdated.

(3): hover: Sets the style sheet properties of an object when it hovers over it.

(4): Active: Sets the style sheet properties of an object when it is activated by the user (an event that occurs between mouse clicks and releases).

The correct order of four properties for hyperlinks in CSS is:

A:link {}
a:visited {}
a:hover {}
a:active {}

Pseudo-class names are not case sensitive, but are required in the definition order. : hover must be placed: Link and: Visited is valid after: active must be placed: hover is valid after.

Notes

By default, the text color of the hyperlink you create is blue and underlined, and then it becomes purple after you access it. If you want to modify this color, you need to style the A:link, a:visited, A:hover, a:active states of the hyperlink with a CSS style.
Example

<style type= "Text/css" > 
a{text-decoration:none} without underscore 
a:link{color:red} 
A:visited{color:blue} 
A:active{color:yellow} 
a:hover{color:green;font-family: italics; font-size:20}
