=== Document type declaration ===

HTML documents are required to start with a d[[Document type declaration|ocument type declaration]] (informally, a "doctype"). In browsers, the doctype helps to define the rendering mode—particularly whether to use [[quirks mode]].

The original purpose of the doctype was to enable the parsing and validation of HTML documents by SGML tools based on the [[Documentdocument type definition]] (DTD). The DTD to which the DOCTYPE refers contains a machine-readable grammar specifying the permitted and prohibited content for a document conforming to such a DTD. Browsers, on the other hand, do not implement HTML as an application of SGML and as consequence do not read the DTD.

[[HTML5]] does not define a DTD; therefore, in HTML5 the doctype declaration is simpler and shorter:<ref>{{cite web |url=https://www.w3.org/TR/html/syntax.html#doctype-syntax |access-date=2013-08-19 |title=The HTML syntax |work=HTML Standard }}</ref>
