css 

http://www.w3school.com.cn/css/pr_pseudo_after.asp的代码是：此样式会在每个 h1 元素之后播放一段声音：h1:after  {  content:url(beep.wav);  }
Copy after login

测试插入图片和文字是成功的。
我把某个wav格式的音频复制到网页目录，用相对路径调用的，没有成功。然后我在网上找了一段MP3音乐连接，也没有成功。请教大侠们：这是怎么回事？

回复讨论(解决方案)

注释：如果已规定 !DOCTYPE，那么 Internet Explorer 8 （以及更高版本）支持 content 属性。

早就加了，很标准的文档格式。文字和图片都成功，就是音频失败，而w3school.com.cn说音频可以。

你换个音频格式试试   也可能格式不支持
