谱乐在“若干特效”专题中曾经提及片头广告，其实她还有另外一种表现形式，由于使用非常多，技术思路富有启迪性，谱乐在这里把她单独作为一个专题予以讲解，同时这也是一个 WMP 6.4 以下版本的实例。本例是以一个 Flash 文件作为片头广告，如此的方法思路同样适用于 Real 。

    代码如下：

＜html＞
＜head＞
＜title＞aboutplayer.com◆谱乐视听◆＜/title＞
＜style type="text/css"＞
.player {
 line-height: 20px;
 color: #000000;
 font-size: 12px;}
.realplayer {
 color: #89A4FF;
 font-size: 12px;
 background-color: #000000;
 border: none;
 height: 18px;
 background-position: bottom;}
