Each HTML document must begin with a document type declaration that declares which version of HTML the document adheres to. HTMLİ4.0 comes in three flavors, each with a different DOCTYPE:
HTMLİ4.0 Strict is a trimmed down version of HTMLİ4.0 that emphasizes structure over presentation. Deprecated elements and attributes (including most presentational attributes), frames, and link targets are not allowed in HTMLİ4.0 Strict. By writing to HTMLİ4.0 Strict authors can achieve accessible, structurally rich documents that easily adapt to style sheets and different browsing situations. However, since many browsers lack full support for style sheets, HTMLİ4.0 Strict documents may look bland on common visual browsers such as Netscape Navigator 3.x.
The document type declaration for HTMLİ4.0 Strict is
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"
"http://www.w3.org/TR/REC-html40/strict.dtd">HTML 4.0 Transitional includes all elements and attributes of HTMLİ4.0 Strict but adds presentational attributes, deprecated elements, and link targets. HTMLİ4.0 Transitional recognizes the relatively poor browser support for style sheets, allowing many HTML presentation features to be used as a transition towards HTMLİ4.0 Strict.
The document type declaration for HTMLİ4.0 Transitional is
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
"http://www.w3.org/TR/REC-html40/loose.dtd">HTML 4.0 Frameset is a variant of HTMLİ4.0 Transitional for documents that use frames. The FRAMESET element replaces the BODY in a Frameset document.
The document type declaration for HTMLİ4.0 Frameset is
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Frameset//EN"
"http://www.w3.org/TR/REC-html40/frameset.dtd">
