CSS z-index problem, urgent! ! ! _html/css_WEB-ITnose

CSS HTML video z-index

Above is a navigation, below is a video, and then there is a secondary menu in the navigation. When it is displayed, it is always displayed below the video. I am very distressed. Adding z-index to them has no effect. I guess I didn't add it. Please give me some advice. Thank you.


The effect after adding video



The effect without adding video

Add an attribute to the flash

<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&amp;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&amp;image=./images/cit_video.jpg" height="273" width="964">            </object>

Change it to:

<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&amp;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&amp;image=./images/cit_video.jpg" height="273" width="964">            </object>

Actually, I just add 67cb30352c2240711aad04a29d9bbf22
and an attribute wmode="transparent"
