CSS构造超链接

1. 超链接边框
2. 派生超链接
3. 属性选择器超链接
4. 动态超链接
5. 图像翻转超链接
6. CSS工具提示

   1.给链接加上边框

       A:link {

           Color: #f00;

           Text-decoration: none;

           Border-bottom: 1px dashed #333;

           Line-height: 150%;

   }

    

   2.在文章段落中加上超级链接

       A:link {

           Color: #f00;

           Text-decoration: none;

           Border: 1px solid #333;

           Background: #ccc;

           Padding: 2px;

           Line-height: 150%;

   }

    

   3. 用背景图象添加记号

       A:link {

           Color:#f00;

           Padding: 0 15px 0 0;

           Background:url(images/arrow.gif) no-repeat right center;

   }

   A:visited {

       Color:#999;

       Padding: 0 15px 0 0;

       Background:url(images/checkmark.gif) no-repeat right center;

   }

    

   4.利用派生来影响链接

       P a:link, p a:visited, p a:hover, p a:active {

           Color:#f00;

   }

   Ul a {

       Color:#000;

   }

    

   5.利用图片作为下划线

       A:link, a:visited {

           Color: #666;

           Text-decoration:none;

           Background: url(images/underline1.gif) repeat-x left bottom;

   }

   A:hover, a:active {

       Background:url(images/underline1-hover.gif);

   }

    

   6.突出显示不同类型的链接

       .external {

           Background:url(images/externalLink.gif) no-repeat right top;

           Padding-right: 10px;

   }

    

   7.使用属性选择器来做链接

   a[href^="http:"] {

           background:url(images/externalLink.gif) no-repeat right top;

           padding-right: 10px;

   }

   a[href^="mailto:"] {

           background:url(images/email.png) no-repeat right top;

           padding-right: 13px;

   }

    

   8.创建按钮和翻转

       a {

           Display: block;

           Width: 6em;

           Padding: 02.em;

           Line-height: 1.4;

           Background-color: #94b8e9;

           Border: 1px solid black;

           Color: #000;

           Text-decoration: none;

           Text-align: center;

   }

   a:hover {

       background-color: #369;

           color:#fff;

   }

    

   9.具有图象的翻转

           a {

           Display: block;

           Width: 200px;

           Height: 40px;

           Line-height: 40px;

           Background-color: #94b8e9;

           Color: #000;

           Text-decoration: none;

           Text-indent:50px;

           Background: #94b8ea url(images/button.gif) no-repeat left top;

   }

       A:hover {

           Background: #369 url(images/button_over.gif) no-repeat left top;

           Color: #fff;

   }
