They were tested on Netscape 4.79, Netscape 6.1 (Mozilla 5.0), Konqeror 2.2.1, Opera 6.0 (all of these on a GNU/Linux system with X 11) and Internet Explorer 5.0 (Windows 2000). Netscape 4.X is notorious for CSS bugs, so we just strove to keep the pages readable. It looks better in any of the other browsers, but we do not expect you will miss anything because of Netscape 4.X.
The language in which you see the pages is chosen using the
language preferences in your browser settings (using content
negotiation
). The available languages are German and English.
The default is German.
The pages were put on the Web in June 2002.
