Is html 5 <! DOCTYPE html> equivalent html 4 transition method?

If I installed doctype in HTML 5 <!DOCTYPE html>, this will set browsers to standard mode.

Does this mean that most modern browsers will behave as if they were in HTML 4.01 Transitional mode?

The browser does not actually have "HTML 4.01 transition mode." They have a “standards” mode and historical modes, “quirks” and “almost standards” for most browsers, as well as many earlier IE rules for IE.

"HTML 4.01 Transitional" doctype, " " SYSTEM "quirks" .

No, they are not alike. Although HTML 5 Doctype is still a draft. But if you test your code for HTML 5 compliance checking, it will not support legacy html 4 attributes or tags. In addition, new HTML 5 tags will only be supported in HTML 5 format when you check your code. You can check it out at this link: http://validator.w3.org/
