StyleSheet macht nicht das, was es sollte...

Hi,

Richtig wäre aber trotzdem:
background-image:url("images/n_hov_bg.png");

Das ist genauso richtig wie

background-image:url('images/n_hov_bg.png');
und
background-image:url(images/n_hov_bg.png);

Siehe auch http://www.w3.org/TR/REC-CSS2/syndata.html#value-def-uri, wo es heißt:

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.

Beachte das Wort "optional".

cu,
Andreas
