DIV transpancy

I know there is an CSS option : background:transparent

but, how i can make a background be white color, and only be transparent 20%?
like that fill thing in photoshop if you get me...

 

opacity:0.2
Actually, probably, 0.8 is what you want.

 

transparent (CSS) have 2 different format for Firefox browser and IE.
For details maybe you can see this CSS :

 

That has not been true for quite some time. opacity works fine in Firefox, Opera, Safari but, of course, not in IE8.

 

He's asking for just the background, by default Opacity effects the entire element and it's children. If you just want the background transparent you are either stuck using an alpha transparency .png (fat, bloated, another file handshake) or the technique I just wrote about a day or two ago.

Which is bloated markup, but at least means you don't have to resort to alpha .png.

 

There is always

 #div { background: rgba(217,217,217,0.7; } 

Code (markup):

Giving you a grey opacity with 70% opacity (Not compatible in IE or earlier versions of FF )

Just another alternative depending on your audience!
