CSS 文件的样例代码:

<style type="text/css">
<!—
br{ background-image: url(http://Fred.com/ImageFile/Q.gif); background-position: top right; background-repeat:no-repeat; }
p { text-indent: 2em}
body { font-family: "宋体"; font-size: 12px; color: #000000; margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px}
table { line-height: 20px;}
a:link { text-decoration: none}
a:visited { text-decoration: none}
a:hover { text-decoration: underline}
a:active { text-decoration: none}
a.1:link { font-size: 10px; color: #oooooo; text-decoration: none}
a.1:visited { font-size: 10; color: #3366cc; text-decoration: none}
.blue {font-style: italic; font-size: 10.5pt; line-height: 20px; letter-spacing: 5em; font-weight:bold}
.h1{font: italic bold "Arial"; word-spacing : 10px}
-->
</style>

  这里尤其要注意的是a:link a:visited a:hover a:actived 的排列顺序一定要严格照上面的样例代码,否则或多或少会出问题。另外我们规定重定义的最先,伪类其次,自定义最后,便于自己和他人阅读!
