<a></a>组成的,可以是文字或图片;
通过使用伪类能对超链接进行修饰;
伪类是一种特殊的选择符,能被浏览器自动识别;
最大的用处是在不同状态下能对超链接定义不同的样式效果,是 CSS 3本身定义的一种类;

例子 1:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>超链接样式</title>
<style type="text/css">
a{
color: #C09853;
text-decoration: none;
}
a:link{
color: #353535;
text-decoration: none;
}
a:hover{
color: blue;
text-decoration: underline;
}
a:active{
color: #666666;
text-decoration: none;
}
</style>
</head>
<body>
<center>
<a href="#">电影</a>
<a href="#">电视剧</a>
<a href="#">综艺</a>
</center>
</body>
</html>

例子 2:给超链接加入提示内容
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>超链接样式</title>
<style type="text/css">
a{
color: #C09853;
text-decoration: none;
}
a:link{
color: #353535;
text-decoration: none;
}
a:hover{
color: blue;
text-decoration: underline;
}
a:active{
color: #666666;
text-decoration: none;
}
</style>
</head>
<body>
<center>
<a href="#" title="节假日购票享8.5折优惠">电影</a>
<a href="#">电视剧</a>
<a href="#">综艺</a>
</center>
</body>
</html>

将图片作为背景图添加到超链接中,这样超链接能有更加精美的效果;
使用 background-image 属性来实现;

<style type="text/css">
a{
background-image: url(img/1.jpg);
width: 95px;
height: 35px;
color: #0055AA;
text-decoration: none;
