1、需求分析一代码
<body>
<bgsound src = "天仙子.mp3" loop = "-1"></bgsound> 打开页面自动播放页面,循环播放
<embed src = "天仙子.mp3" autostart = "false" volume = "0" loop = "5"></embed>
打开页面播放设置,控制播放
<marquee behavior = "alternate" >我来啦</marquee> 弹幕交替
<marquee behavior = "scroll" scrollamount = "50" loop = "3" scrolldelay = "1000">我来啦</marquee> 弹幕循环滚动
<marquee direction = "up" behavior = "slide" width = "300" height = "300" bgcolor = "#ff9999" >我来啦</marquee>
</body>
