answer:XHTML is more strict and more modern. Actually, it’s just HTML but to be interpreted as XML instead of XGML, which indeed basically means that it’s more strict (gotta love acronyms, don’t you? :). The only people who’d want to write HTML are people who have never been using XHTML and don’t feel like going through the trouble shaking off their bad habits. Also, because XHTML is more strict, it can be parsed faster by web browsers. Bottom line: you’ll want to go with HTML.
