Re: [css3-background] possibly too late for last call, but: background-opacity?

Thanks for your reply and your drop-shadow proposal page! Thats a very  
flexible approach.

Could you target specific background images in a multi-background  
element? For example:

  opacity:0.5; apply-to(opacity, background-image(1,2,4) + background- 
color);

and would these properties be able to be animated?


regards,

Lee
