HTML 5 is an evolving specification which has not yet achieved W3C recommendation status; if you use it, please be aware that what the validator tells you is valid today it may well you is invalid tomorrow (and vice-versa). HTML 4.01 is the most recent version of HTML to have achieved full W3C Recommendation status. It is stable, unchanging, and compatible with all modern browsers. XHTML is a re-formulation of classic HTML as a dialect of XML; whilst this seemed to be the W3C's preferred route for the evolution of HTML in the past, that would no longer seem to be the case. Therefore : If you want the latest features and are willing to risk your documents ceasing to be valid in the future, use HTML 5 If you want stability and need none of the features that HTML 5 offers, use HTML 4.01 (ideally HTML 4.01 Strict) If you want compatibility with XML, use XHTML 1.1 These are personal opinions and are not intended to represent the W3C's views; I am not a member of the latter.
