There is a CSS error in the following file:
(and in other languages, like "de", too). This is included in every Wikipedia page.
The error is in the first line: "white-space: wrap;". There is no value "wrap" for the white-space property in CSS. In no version of CSS and neither Firefox nor Opera knows this (they throw errors). I don't know about the IE, but I didn't find anything on google about this.
Version: unspecified
Severity: enhancement
