Unbekanntes Attribut ?

[MudGuard]

Hi,

CSS ist nicht auf die Verwendung mit (X)HTML eingeschränkt.
Klassenselektoren jedoch theoretisch schon. Oder ist mir da wieder was entgangen? :-)

Wieso?

UAs may apply selectors using the period (.) notation in XML documents if the UA has namespace specific knowledge that allows it to determine which attribute is the "class" attribute for the respective namespace. One such example of namespace specific knowledge is the prose in the specification for a particular namespace (e.g. SVG 1.0 [SVG10] describes the SVG "class" attribute and how a UA should interpret it, and similarly MathML 2.0 [MATH20] describes the MathML "class" attribute.)

cu,
Andreas
