I could potentially see this >as a result of parsing, but it's a bit disconcerting. Yes, you get a normalized version of the input. If you have multiple physical style sheets, the validator combines them to a single style sheet, if you have a 0 length like 0px it will remove the unit, if a property can have multiple values in any order it will pretty print the values in a "normal" order, etc. It's probably not ideal, but it does not seem to be critical... >Now consider this example: > >p { font: normal italic 12pt georgia, serif; } > >Valid, but it results in an error. Yes. I have filed a bug report for it, see http://www.w3.org/Bugs/Public/show_bug.cgi?id=777 This would in CSS 2.1 be equivalent to font-variant: normal; font-weight: normal; font-style: italic; font-size: 12pt; line-height: normal; font-family: georgia, serif; What the Validator currently does is to check whether the first value is a legal <'font-style'> and if it is, it assigns the value to its internal representation for the font-style part of the font property and then continues to look for legal values. Since it already determined the value for font-style it will not check it again, but rather for <'font-variant'> and <'font-weight'>. Since that fails it expects the next value to be a <'font-size'> as it would be required by the grammar. That fails as "italic" is not a legal <'font-weight'> and hence the error message. See the code from line 131 to 186 in http://dev.w3.org/cvsweb/2002/css-validator/org/w3c/css/properties/CssFont.java?annotate=1.2 >Next and last example, taken from >http://css.researchkitchen.de/validation.html: > >div { border: 1px solid c85; } > >Passes as valid, though the color value is clearly invalid. See my earlier bug report http://www.w3.org/Bugs/Public/show_bug.cgi?id=287 >More thoughts and an interesting observation: >http://www.minzweb.de/en/pages/sitetopics/archive_permalink.asp?id=42 This is, in part, covered by http://www.w3.org/Bugs/Public/show_bug.cgi?id=737 and I am glad to tell you that this is fixed (though the online version has not been updated yet). The style sheet will now be considered valid regardless of whether usermedium=all or no usermedium is specified. Ok, this is not yet ideal, but I feel we are getting closer :-) I've filed another bug report for <http://css.researchkitchen.de/validation.html>, http://www.w3.org/Bugs/Public/show_bug.cgi?id=778 This might turn out to be some kind of setup problem... Thanks for your report!
