怎样设定部份文字链接的样式表
div { font-family: "Arial", "Helvetica", "sans-serif"; font-size: 9pt; color: #000000; text-decoration: none}
a { font-family: "Arial", "Helvetica", "sans-serif"; font-size: 9pt; color: #000000; text-decoration: none}
a:hover { font-family: "Arial", "Helvetica", "sans-serif"; font-size: 9pt; color: #FF0000; text-decoration: underline; border-color: #0000FF black black}
td { font-family: "Arial", "Helvetica", "sans-serif"; font-size: 9pt; color: #000000; text-decoration: none}
我需要有些地方是白字，显示链接后变黑；有些地方黑字显示链接后变白字

设置两个不同名的hover类，
在实现不同效果的地方调用响应的类。
