dtdhtml

DTD is a set of syntax rules for tags. It is part of the XML1.0 version specification, is the verification mechanism of html files, and is part of the composition of html files.

DTD: three document types: S (Strict), T (Transitional), F (Frameset).
Strict: Use this type if you need clean markup without clutter in the presentation layer. Please use with Cascading Style Sheets (CSS)
Transitional: The DTD can contain rendering attributes and elements that the W3C expects to be moved into the style sheet. Use
Frameset if your readers are using browsers that don't support Cascading Style Sheets (CSS) and you have to use HTML's rendering features: DTD should be used for documents with frames. Except that the frameset element replaces the body element, Frameset DTD is equivalent to Transitional DTD

html5 basically does not have the strict requirements of XHTML 1.0 Transitional, and simplifies many things and can be used directly

HTML5
