A few notes about webpages and formatting

Theory

Obviously, a user of scientific webpages (you) want information to be fast, concise and informative.
So we stick to clearly defined standards for the computer language of web pages: the W3C consortium defines them.
By using standards, all browsers (Explorer, Netscape, Mozilla, Opera, etc.) have a fair base to display the page contents correctly.
W3C offers an HTML and Cascading Style Sheets (CSS) checker at validator.w3.org, and jigsaw.w3.org/css-validator, which allows to check a web page for standard compliancy.
To have this page checked for CSS compliancy, feed this page to the W3C CSS checker.

Beside the standard HTML language, we use Cascading Style Sheets (CSS) and JavaScript for enhanced readibility. Without them, these pages should still be functional.

Language selection

Most pages are available in English and German, some pages are currently in German only. Sorry about that, they will be added soon.
Which version is served depends on your language preferences, which is set in your browser configuration.
Netscape offers language selection at the menu Edit - Preferences - General - Languages.
Furthermore, most pages allow manually selection by clicking on the flag displayed at the lower end of the page.
