Making other cells translucent?

I just read up on how to make some parts of my forum Translucent (from here: Cells Translucent Tutorial).

And is it posible to make other parts of my forum translucent? I can not figure out the code to do it...
The code in the tutorial makes the categorys, who is online, and statistics translucent, but I would like other things to. If someone could please help.

You might want to tell exactly which places you want to do. Maybe then someone can answer you.

Well I found out that Td.row1 is Background Color 1 in the colors, and Td.row2 is Background Color 2, still don't know what one Td.row 3 is.

But I would like my Header Background Color to be, my Rollover Color, Body Line, Forum Line, Row Line Color to be, Category Header, Category Background, and Category Border, and Background 3, I think that is all of them I want. Does that help any?
