Css Transparencies how do i do?

recently i have seen sites with a cool background and above a div or table with a nice transparency, my question is, how do i make that?

In CSS Style:

background: transparent;

<input name="txt" type="text" id="txt" value="This is text on transparent text box" style="background: transparent;">

And thats all i got problem with find this too, some time ago.

hey thankyou buddy!Even I am working on my sites design right now and I was looking for something like this only.....thanks a lot!

see the complexspiral demos at css/edge ( http://meyerweb.com/eric/css/edge/ ) for great justice. IF you thought you'd seen transparent backgrounds....Incidentally, i've never ever seen the 'transparent' property - i had to look it up. In any case, are you sure it's what you want? It shows the background of the body element as close as i can determine, or whatever it is.

thanks, helpful, but yesterday i fotgot to ask if i can control the alpha channel, and the color of the transparency, thanks!

It is possible to control the alpha channel, but I'm not sure about the color.

In the part where you make the thing that you want to be transparent, add "opacity: .90;" or however transparent you want it. It works like a percent, .00 is not opaque, 1.00 is completely opaque, .50 is half, etc.

I don't think that it's technically valid CSS, though. I believe that it will be in CSS3 (whenever that comes out). There are also some other filters that you can use which are described at http://forums.xisto.com/no_longer_exists/ (including alpha, I'm not sure if that's better than opacity:).
