CMS Made Simple Forums

I am somewhat entirely new to the CSS world and stylesheets, so I'm hoping someone here can help me with my problem.

What I'm looking for is a way to create a transbox for the content on the pages . It would just be like regular content put on a page, except it's in a box that is translucent, so you can still see the background, but the box is providing enough of a foreground where the text can be read in more clarity.

I'm sure some of you know what I'm talking about...hopefully, lol.

Any help in this matter would be appreciated, thanks.

If you don't care about InteretExplorer you could use rgba CSS property http://www.css3.info/preview/rgba/.
Else you could use a png image (like 5x5px in size) with 50% or something transparency and color that you want to have, then use background CSS property http://www.w3schools.com/css/css_background.asp to add that image as background of a div you want this effect to have.

I'd like to fit in as much compatibility between browsers as I can, so I'll try your second bit of advice and see how it turns out. Thanks.
