Adobe abandoned the Spry framework late last year. So it is unlikely that you will see Spry in future releases of DW. I no longer use Spry for anything.
Opacity can be controlled very nicely with simple CSS code and a couple of MS filters for older IE browsers.
Thanks you very much Nancy..! really helpful !
I should have understood by seeing all the bad comments on spry..
( I guess I couldn't be harse to find another way...! )
Anyway thanks for the link aswell, I just want to share this other one that I found which has made the fading effect succesful for my website - > http://bavotasan.com/2011/a-simple-fade-with-css3/
