HTML <!DOCTYPE> tag




Advertisements

Function:

The HTML !doctype tag is used for specifying which version of HTML the document is using. This is referred to as the document type declaration (DTD).

HTML 4.01 has 3 possible doctypes: HTML 4 Strict, HTML 4 Transitional, and HTML 4 Frameset. Every HTML document you create should have one of these three DTDs.

NOTE: The <!DOCTYPE> tag does not have an end tag! 

HTML 4 Strict

This document type includes all HTML elements except those that have been deprecated, and those that appear in frameset documents.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
	"http://www.w3.org/TR/html4/strict.dtd">

HTML 4 Transitional

This document type includes all HTML elements including those that have been deprecated.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
	"http://www.w3.org/TR/html4/loose.dtd">

This document type includes all HTML elements in the transitional DTD as well as those in framed document.
