Semi-Transparency Just For The Tables

How can I give transparency just for the forum tables please? I have Punbb. thanks

Can someone please help with this.....
I already tried the instruction thread for this and it still didn't work. Maybe because I have a Punbb. I also did the search for this and still nothing works.

I would like to know how I can give the forum tables with a little transparency please?? Or at least try to assist me?

Please keep the Color to the default as it’s for staff members use only. This is your 3rd reminder about this and it turns into a warning. Please don't use color.

Could you please explain more about this?

ok, sorry.

Can someone show me how I can give just the tables with a little trasnparency? I have a punbb.
