What is an HTML Doctype Definition (DTD) Declaration?

The HTML DTD declaration is a portion of HTML code placed at the top of an HTML document and identifies the rules for the markup language used in the document, so that website browsers like Internet Explorer, Mozilla Firefox, Google Chrome, etc. can render the HTML document correctly.

Is the Declaration an HTML tag?

This is an excellent question, and a misconception. The HTML DTD declaration is not an HTML tag; it is an instruction to the web browser that tells the application what version of HTML the page is written in.

The declaration refers to a Doctype Definition (DTD) which specifies the rules for the markup language, so that the browser renders the content correctly.

What does HTML DTD stand for?

HTML DTD stands for Hyper Text Markup Language Doctype Definition.

Where should the HTML DTD Declaration be placed?

The HTML Doctype Declaration (DTD) should be the very first thing in an HTML document, even before the html tag.
