What is Doctype Tag Represents in HTML?

2/23/2012

The <!DOCTYPE> declaration must be the very first thing in your HTML document, before the <html> tag.

The <!DOCTYPE> declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.

The <!DOCTYPE> declaration refers to a Document Type Definition (DTD). The DTD specifies the rules for the markup language, so that the browsers render the content correctly.

Notes: Always add the <!DOCTYPE> declaration to your HTML documents, so that the browser knows what type of document to expect.
