The background of a Flash movie can be set to display as transparent.
The swf file on the left is not transparent. The swf file on right is set to
transparent. This script works only in IE 3.0 and above. It does not work in Netscape.
Transparency allows the background color or image of the HTML page that contains the Flash movie to show through.
To make a transparent movie is very simple. Just add the
wmode attribute and set it to
transparent, as below.
<EMBED src=transparent.swf width=120 height=30 type="text/html;
charset=iso-8859-1" bgcolor="#000000" wmode="transparent"
