Yann Ramin Yann Ramin The W3C is hardly an impartial third party. They wrote the freaking spec, and they still love them some XHTML and push it every chance they get, but they pretty much doomed it with 2.

Not backward compatible? WTF, y'all. Or , you can ignore all this and use the following instead, soon anyway :. This answer to "any reason not to start using the HTML 5 doctype? I've written an article that explains how doctypes are involved in rendering mode selection. There is a lot of misinformation around doctypes.

The confusion stems from the fact that doctypes originally was intended for one purpose to identify the DTD, ie. Doctype declarations are only used for one thing in todays browsers, that is switching between quirks rendering mode and standards rendering mode for CSS.

Quirks mode rendering is backwards compatible with some old rendering bugs in older browsers, and is mostly useful for legacy content you dont want to fix.

New content should always use standards mode, since it renders more correct and consistently among browsers. There is still rendering differences between browsers when using standards mode, but there are much worse in quirks mode. The rendering mode is basically selected like this:. Historically doctypes were intended to declare which version and subset of HTML were used. HTML4 defines several versions, where "transitional" allows a number of elements ans attributes that like FONT is not allowed in "strict".

A browser could theoretically process "strict" documents different than "transitional"-document. However no browser actually does this. Edit: scunliffe points out that IE8 will have yet another rendering mode, "IE8 standards" mode. If you don't set it to XHTML, or "strict" you'll be living in a world of hurt when it comes to IE even if you set it, you'll still be hating on IE, but it does make it a lot better.

For new pages it should , times when you need to be compatible with browsers which don't support standards mode are very rare today.

Does it support the features I need? Strict doctypes avoid most features that should be handled with CSS.
