Background color + text

[RockDemon]

Hi!

probably an easy answer to this, but I could'nt find anything in the FAQ.

I set black as my background color, and white as text color, but still, when trying to register a new post, the text is black on black background. I know that it is because of this code:

body {
margin: 0px;
font-family: Verdana, Arial, sans-serif;
color: black;
font-size:11px;
}

But that code is generated by the guestbook as far as I can see?

Thanks
