In daringfireball, BareBones’ John Gruber posts detailed notes on how differently the W3C’s HTML validator works compared to the one built into BBEdit. In essence, both validators report different classes of errors, but that doesn’t mean that one is more broken than the other. The W3C’s will even let you set width=”fred flintsone” on a table cell without complaining. Neither validator reports false positives though – may as well use them both.
Validate? Sounds wonderful. I’m all about validation. Oh wait – I don’t have time to update 5-year-old designs, let alone validate new ones.
