Facebook Flash Application background color doesn't show up

How to make the flash background color show up开发者_Python百科? I tried swfbgcolor doesn't work...

Try looking at this link :

http://wiki.developers.facebook.com/index.php/Fb:swf

In the fb:swf try this :

<fb:swf 
swfbgcolor="000000" 
imgstyle="border-width:3px; border-color:white;" 
swfsrc='http://www.youtube.com/v/xxxxxxxxxx' 
imgsrc='http://img.youtube.com/vi/xxxxxxxxxx/2.jpg' 
width='340' height='270' />

Now set the swfbgcolor with what you want in hex and your done :)
