Embedding
object, embed, and css z-index
Based on the information here: http://joshuaink2006.johnoxton.co.uk/blog/82/flash-content-and-z-index
I have found that this code will allow me to embed a flash file and have it respect my CSS z-index rules in Firefox 3, Safari 4 and IE8:
<object width="930" height="330"> <param name="wmode" value="transparent"> <param name="movie" value="/flash/myflashthing.swf"> <embed src="flash/myflashthing.swf" width="930" height="330" wmode="transparent"/> </object>
The key seems to be the "wmode"="transparent" parameter
