i used w3Schools example (for image opacity), but validtion says theres a problem.

un/validation:
http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fdungeonpsyche.com%2F

specifically saying:

Sorry! We found the following errors
URI : http://dungeonpsyche.com/
53 img Property opacity doesn't exist : 0.4
54 img Parse Error - opacity=40)

does any one know where to find, or how to write the valid format?
thanks a million

looks like that is part of CSS3 with is not supported some browsers yet (or has limited support). i think firefox allows it but ie does not.

the css validator might not be allowing for css3 specific items yet.

hey!, your a pretty smart cool guy, thanks!
