可以有marquee的。

你可请参考 http://www.htmlcodetutorial.com/_MARQUEE.html

我看了. 我也找到一组代码. 我想要问, 这个script 会不会太麻烦复杂?
因为我有看过有些同样function, 但没有那么长的script. 我不是很了解为什么有些要那么长, 有些又可以那么短.
另外我想要改变font color 就改不了, 不知道哪里出了问题还是一直是蓝色. 可以帮我看看吗?

可以试试加红色那一断。。。
#pscroller2 a{
text-decoration: none;

}
.someclass{ //class to apply to your scroller(s) if desired
}
#pscroller2 a:Link {
color: #333333; /*change your color*/
}

我看我没办法用这个script 了, 因为在firefox 没办法显示正常

你有好介绍吗? 我想要一排scrolling text with links. 因为我要做news update.

klvn

no idea.
我很少用这个scrolling text
