用双层marquee制作出来的飘浮广告效果，非常棒！
<html> <head> </head> <body> <marquee behavior="alternate" height="400" direction="up" scrollamount="3" scrolldelay="30" width="500" bgcolor="#3399FF"> <marquee behavior="alternate" height="50" direction="left" scrollamount="3" scrolldelay="30" width="100%"> <font style="font-size: 35px">Ouyang</font> </marquee> </marquee> </body> </html>
复制下来试试！
