I'm interested in knowing what browsers apply as the default doctype on a page that does not have this element. For example www.isuzu.com does not have a doctype if they were to add one and didn't want to messup the layout of their site what would be one that matches their current rendering.. Basically browser must be applying one by default.. but which one is it?
Refer: http://www.w3schools.com/tags/tag_doctype.asp There is no default type.. a more general one would be the Transitional DTD.
