Dhtml Opacity how stable is opacity

I'm working on a new site, and would really like to use the opacity functions in dhmtl but i'm just wondering how stable it is. It is super important that most browsers see it so i've found a script for both mozilla ( very difficult to find) and one for ie. but now i'm just at a cross roads. Anyone have any thoughts, has every used it and it all went bad. Seems stupid but the site i'm working on is like over 500 pages and i don't want to start out bad.

wow 500 i wouldn't worry about using dhtml i say go 100% php with that many pages. but opcity, i havn't really seen and or used it but with the amount of content your asking dhtml is going to fry your page due to loading time it takes.

Good Job ,Some Script doesnt work with Firefox or mozilaWhat is DHTML and what is JS + HTML ?I Think if you want to build one web site with run script in all browsers you must programming in Js or php or asp !PLz tell me more about Browsers and PagesI remember make one site .when i looking with IE its true but when i looking with firefox my tabales is not true working i hate this kind of browserswhy programmers dont fix this problem ?Its not web designer problem its browser programmer

I dont really know if this is what you wanted, and I cant really check it out cause I have to go right now. I remember reading this article at alistapart about png transparency combined with dhtml which will let you have cross browser transparency, which I hope is what youre looking for. Well I have to go now.
