I don't think it is invalid CSS - the closing parenthesis ')'
terminates the url value. The white-space is optional. I think.
For keywords, it is of course different 'top right' is not the same
as topright.
See for more:
And as for the logic of HTML tags, it would undeniably be a better
validator if it could warn "tag-based declaration doesn't match any

typo.
The validator doesn't look/care about what you put in a selector.
What if you are using that css file for some xml document that has an
element 'navbar' within its namespace ?

Hi,
It's CSS validator. It doesn't validate cross-browser compatability or the
logic (or existence of) of HTML tags.

[WSG] While we're on the subject of validators...
I recently came across two niggling CSS errors:
1)
body { background: url('image.gif')no-repeat top }
Here, the coder has left no whitespace after the URL in the shorthand
"background" declaration.
Firefox is OK with it, IE doesn't display the image.
2)
#right navbar {width:400px;}
Here the coder meant #right_navbar but missed the underscore. Obviously
it doesn't work.
The thing is, the W3 CSS validator passes them both. It even *fixes* the
missing space in the first example and displays it like this:
body {
background : url('image.gif') no-repeat top;
}
The second case is a little more complex, because logically, anything
which isn't a class or an id should be an HTML tag. And there's no HTML
tag "navbar". Yet. So that can't be valid CSS for any valid HTML
document.
Should I report this to someone?
