spacing between page and browser window gone

Hi folks,

I got the blog up and running just the way I want it to, there is however one tiny beauty mark.

Normally there is a few pixels between the browser window and the actual body of the site.

However, when I implement the blog function that spacing is gone.

/* Short and sweet */
define('WP_USE_THEMES', true);
require('c:\\domains\\fortherestless.com\\wwwroot\\forms\\diary\\wp-blog-header.php');
?>

Does anyone know how to resolve this ?

Here’s the screen.css, used on the website
