[How To?] I need to make the forum transparent

[You_N_Me]

I need to make my forum transparent so I can see the background image but the other threads I've found use a code 

background: #000;
opacity: .70;
-khtml-opacity: .70;
-moz-opacity: .70;

Which makes the entire forum transparent which I do not want I just want the background of the forum to be transparent so the image behind can be seen.

I also need to know how to change the text color for each section so it'll be visible with the background image.

I currently have it set to the code above so you can see what it's doing.

Doesn't work, I might just use a different theme.
