D. The HTML 4.0 DTD

Appendix D

D. The HTML 4.0 DTD

The HTML 4.0 standard is formally defined as three SGML Document Type Definitions (DTDs): the Strict DTD, the Transitional DTD, and the Frameset DTD. The Strict DTD defines only those elements that are not deprecated in the 4.0

standard. Ideally, everyone would create HTML documents that conform to the Strict DTD. The Transitional DTD includes all those deprecated elements and more accurately reflects the HTML in use today, with many older elements still in common use.

The Frameset DTD is identical to the Transitional DTD, with the exception that the document is replaced by the tag.
