So-called conditional comments seemed nice, until I wound up with
four additional style sheets just for IE. So I do wonder about the
utility of hiding CSS from the validator?
I mean, I can and do make mistakes in those hidden style sheets
that the validator could catch. As for the non-validating code, well,
my British English spell checker tells me that "color" is spelled
wrongly, but in the context of an article about CSS I would simply
ignore the "error". What is so special about CSS that I need to trick
the validator just to get a passing grade?
Just wondering.
Cordially,
David
