Hi,

Tobias hat jedenfalls rechter als ich, um url(...) gehoeren Anfuehrungszeichen.

Nein, die sind optional.
Zitat:
The format of a URI value is 'url(' followed by optional whitespace followed by an optional single quote (') or double quote (") character followed by the URI itself, followed by an optional single quote (') or double quote (") character followed by optional whitespace followed by ')'. The two quote characters must be the same.

cu,
Andreas
