You can tell that e.g. from a `null` return value from the getProperty- CSSValue(...) method, the empty string (since it is not a legal value for any property) from getPropertyValue(...), and from going through the .items(0 .. .length) names. You cannot do that with the return value of getComputedStyle() however, since all properties have a computed value. -- Björn Höhrmann · mailto:[EMAIL PROTECTED] · http://bjoern.hoehrmann.de Weinh.
