CSS with Black Background

[Big Ben]

Have half finished a new site. All pages need black background. All is well and good EXCEPT: Pages which have "table headers" sich as: login- "returning customers," "company details" or checkout_payment and checkout_shipping headers "payment methods" "order comments" etc as Titles to the Boxes on the page DO NOT show these titles in White (The text is present but invisible black.)
I have made every css change i can think of and all <p> text renders OK but <h1> stays black.
I have tried playing with "define" pages to no avail.
I understand the overide hierarchy pretty well and dont think this is a problem.
I am so pleased with the site otherwise - in a different league entirely to a couple of commercially sold proprietary sites I have experienced!.
Any ideas please.
Version is 1.3.9d but Ive cloned a couple of addon shipping bits, and the old cc module all of which work great.

It's always easier to advise on styling issues if we can see your site live.

Looks like you have fixed it??

No I havent - if you look at the home page log in - press "log yourself in" there are 3 or 4 white bordered boxes which all have the same problem - the top left hand border is incomplete because it is obscured by a "TABLE_HEADING which is defaulted to <h1> and SHOULD be White according to CSS but is actually Black. Same thing happens with similar pages in the Cart and Check out system. Ben

I see (in Firefox):

all in white on the black background. What browser are you using? Have you cleared your cache to see if it is just an old view?
