Definition and usage of pseudo-class selector E:hover:

Set the style of an element when its mouse is hovered.
E elements can be selected through other selectors, such as class selectors, id selectors, type selectors, etc.
Special note: IE6 does not support this selector, but it can support :hover of the a element, that is, it only supports :hover of the a element selected through the type selector.

Grammar structure:

E:hover{ Rules }

Browser support:

IE browser supports this selector.
Firefox supports this selector.
Google Chrome supports this selector.
opera browser supports this selector.

Example code:

<!DOCTYPE html>  
<html>  
<head>  
<meta charset=" utf-8">  
<meta name="author" content="http://www.manongjc.com/article/1323.html" />  
<title>CSS教程</title>  
<style type="text/css">  
#div:hover{color:#F60;}  
.js:hover{color:green;}  
</style>  
</head>  
<body>  
<ul>  
  <li><a href="#">html专区</a></li>  
  <li><a href="#" id="div">div+css专区</a></li>  
  <li><a href="#" class="js">javascript专区</a></li>  
  <li><a href="#">Jquery专区</a></li>  
</ul>  
</body>  
</html>

Use the type selector to set the pre-access style of the hyperlink.

<!DOCTYPE html>  
<html>  
<head>  
<meta charset=" utf-8">  
<meta name="author" content="http://www.manongjc.com/article/1323.html" />  
<title>CSS教程</title>  
<style type="text/css">  
#div:hover{color:#F60;}  
.js:hover{color:green;}  
</style>  
</head>  
<body>  
<ul>  
  <li><a href="#">html专区</a></li>  
  <li><a href="#" id="div">div+css专区</a></li>  
  <li><a href="#" class="js">javascript专区</a></li>  
  <li><a href="#">Jquery专区</a></li>  
</ul>  
</body>  
</html>

Set the style of a hyperlink on mouseover via class selector and id selector. Not supported in IE6.

<!DOCTYPE html>  
<html>  
<head>  
<meta charset="utf-8">  
<meta name="author" content="http://www.manongjc.com" />  
<title>码农教程</title>  
<style>  
div {  
  width:100px;  
  height:50px;  
  background:#ccc;  
}  
div:hover {  
  background:green;  
}  
</style>  
</head>  
<body>  
<div></div>  
</body>  
</html>

The above code can change the background color of a div when the mouse is hovering over it. It also shows that the :hover pseudo-class is not just a scope link to the a element.
