All that matters is that you either have a doctype or you don't.

As far as browser behavior is considered, the two specific doctype strings above have exactly the same effect. In markup validation, they make a huge difference. However, validators have a "doctype override" feature. As a general statement, "All that matters is that you either have a doctype or you don't" is not correct at all. Different doctype strings trigger different browser modes, see http://hsivonen.iki.fi/doctype/ >> These days, just use <!DOCTYPE html> everywhere. If you don't care about validation and your pages are ready for Standards Mode (old pages generally aren't), then <!DOCTYPE html> is simplest. The simplicity helps to avoid stupid mistakes in the doctype string - a single mistyped character there can have drastic effects. > So it's irrelevant? Not at all if validation is considered. > Do pages which validate as HTML 4 strict also validate as HTML 5? No, that's a common misconception. Some examples of valid HTML 4.01 Strict features that cause an error message in HTML5 validation: - the <acronym>, <big>, and <tt> elements - <object> element inside <head> element - several attributes, e.g. align=right in <td> - <meta> tags in general: HTML 4.01 syntax is very liberal, allowing <meta name=myidea content=whatever>, whereas HTML5 specifies a (messy) mechanism for defining allowed variants and declares all the rest invalid. The bottom line is: decide whether your documents will be closer to HTML5 than to (some variant of) HTML 4.01, and select the doctype string accordingly. This is just a practical issue: which choice gives your fewer disturbing error messages about constructs that you use knowingly, so that it is easier to check out the other messages (which may reveal real errors)? -- Yucca, http://www.cs.tut.fi/~jkorpela/ |
