Css youtube视频后面显示的下拉菜单GetInd

我的代码中存在可见性问题。我有一个下拉菜单，可以在youtube视频上看到。结果是菜单显示在youtube视频的后面，而不是显示在前面。请帮忙。谢谢

这是我菜单的代码

<div style="margin-top:-60px;padding-bottom:20px;position:relative;overflow:visible;">

<div class='cssmenu'>

问题：导航中有一个基于CSS的下拉菜单，旁边有一个flash元素。这些菜单可能会“隐藏”在flash对象后面

解决方案：将持有闪光灯的div的z-index设置为1，将持有导航的div的z-index设置为2。（

z-index:1；

和

z-index:2；

） 在flash元素中： 查找flash

标签并添加以下代码：

<param name="wmode" value="transparent">

您需要将此代码插入

标记的正下方，并将代码

wmode=“transparent”

包含在flash

标记中

试试看，祝你好运

在

value=high

或

value=transparent

处找到原始文本？ThanksAn示例

值应为高，并且wmode透明。。这也适用于iframe。您可以跳过参数名称，除非在何处添加它。。它并不总是存在于现有的代码中，而且YouTube会处理其中的大部分内容。
