How to use CSS to remove the underline of a hyperlink

We can use CSS syntax to control the form and color changes of hyperlinks. Why must links be distinguished by underlines and colors? The main reason is mainly to consider 1. People with poor vision 2. People with color blindness. . .

Let's make a link like this: when the link is not clicked, the hyperlink text is not underlined and appears in blue; when the mouse is on the link, it is underlined and the link text appears in red; when the link is clicked, the link No underline, displayed in green.

The implementation method is very simple. Add the following CSS syntax control between and in the source code:

 <style type="text/css">
　　 <!--
　　 a:link { text-decoration: none;color: blue}
　　 a:active { text-decoration:blink}
　　 a:hover { text-decoration:underline;color: red} 
　　 a:visited { text-decoration: none;color: green}
　　 -－> 
　　 </style>

　Among them:
　a:link refers to Normal links that have not been visited;
a:active refers to the link being clicked;
a:hover refers to the mouse on the link;
a:visited refers to the link that has been visited;
text -decoration means text modification effect;
The none parameter indicates that the hyperlink text will not be underlined;
The underline parameter indicates that the hyperlink text will be underlined

font-weight:Normal; /*CSS字体效果 普通 可以改成bold粗体 如果去除此行那么默认是不显示下划线的*/
text-decoration:none; /*CSS下划线效果：无下划线*/
}

a:hover {
color:#4499EE;
text-decoration:none; /*CSS下划线效果：无下划线*/
border-bottom: 1px #0099CC dotted /*CSS加一个只有下边的框 边框为虚线*/
