CSS z-index问题，急急急！！！_html/css_WEB-ITnose

CSS HTML 视频 z-index

上面是一个导航，下面是一个视频，然后导航那有二级菜单，显示的时候，总是显示在视频的下面，我非常的苦恼，给它们加了z-index也没有用，应该是我没加对吧，请各位高手赐教了，谢谢。

回复讨论(解决方案)

为什么没有人帮我解决一下呢？？？请各位大仙帮帮忙吧

给flash那个加一个属性

<object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" height="273" width="943">                <param name="movie" value="./css/player-viral.swf">                <param name="allowfullscreen" value="true">                <param name="allowscriptaccess" value="always">                <param name="flashvars" value="file=http://www.citmd.com/CIT/2013/images/cit2013.mov&image=./images/cit_video.jpg">                <embed type="application/x-shockwave-flash" id="player" name="player" src="Home-CIT%20Conference%202013_files/player-viral.swf" allowscriptaccess="always" allowfullscreen="true" flashvars="file=http://www.citmd.com/CIT/2013/images/cit2013.mov&image=./images/cit_video.jpg" height="273" width="964">            </object>

改为：

<object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" height="273" width="943">                <param name="movie" value="./css/player-viral.swf">                <param name="allowfullscreen" value="true">                <param name="wmode" value="transparent">                 <param name="allowscriptaccess" value="always">                <param name="flashvars" value="file=http://www.citmd.com/CIT/2013/images/cit2013.mov&image=./images/cit_video.jpg">                <embed  wmode="transparent"  type="application/x-shockwave-flash" id="player" name="player" src="Home-CIT%20Conference%202013_files/player-viral.swf" allowscriptaccess="always" allowfullscreen="true" flashvars="file=http://www.citmd.com/CIT/2013/images/cit2013.mov&image=./images/cit_video.jpg" height="273" width="964">            </object>

实际就是加了 
和一个属性 wmode="transparent"
