In [1], I found the following example:
background-image: image(wavy.svg, 'wavy.png' 150dpi, "wavy.gif" or blue);
Should it be image( url(wavy.svg), 'wavy.png' 150dpi, "wavy.gif" or blue); ?
With the CSS21 current parsing rules, function is defined as
FUNCTION S* expr ')' S*
expr
: term [ operator? term ]*
term
: unary_operator?
[ NUMBER S* | PERCENTAGE S* | LENGTH S* | EMS S* | EXS S* | ANGLE S* |
TIME S* | FREQ S* ]
| STRING S* | IDENT S* | URI S* | hexcolor | function
;
So the unquoted wavy.svg is not a string, not a URI (as url(...) is
missing) and not an ident because of the '.' and a CSS21 Parser based on
the latest CSS21 Candidate Rec is unable to parse this declaration.
Depending of the intent, it would be good to either add a url() or to
require quotes.
Thanks,
