What is doctype?
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. In HTML 4.01, the <!DOCTYPE> declaration refers to a DTD, because HTML 4.01 was based on SGML. ... HTML5 is not based on SGML, and therefore does not require a reference to a DTD.
The <!DOCTYPE> declaration must be the very first thing in your HTML document, before the <html> tag.

A document type declaration, or DOCTYPE, is an instruction that associates a particular SGML or XML document (for example, a webpage) with a document type definition (DTD) (for example, the formal definition of a particular version of HTML1.0 - HTML 4.0).
Many people think this is a HTML tag. First of all this is not the HTML tag. It is just a message or instruction to web browser about what version of HTML page that you have written.
The <!DOCTYPE represents web browser which version is the HTML page been written in.It is declared first in the html document.
Following is an example to understand better:
<!DOCTYPE html>
<html>
<body>
<h1 style="color:Blue";>HTML Document </h1>
<p style="color:Pink";>This is paragraph</p>
</body>
</html>

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.
There are subtle differences between different "standards complaint" rendering doctypes, such as the HTML5 doctype (<!DOCTYPE html>, prior to HTML5 only known as the "skinny doctype" which not trigger standardised rendering in older browsers) and other DOCTYPEs such as this one for HTML 4.01 transitional:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
Many of people thinks that <!DOCTYPE> is one the HTML tag but it's not . It's a information given to Web Browser about the version of HTML page that you are working on.
The DTD specifies the rules for the markup language, so that the browsers render the content correctly. HTML5 is not based on SGML, and therefore does not require a reference to a DTD. Tip: Always add the <!DOCTYPE> declaration to your HTML documents, so that the browser knows what type of document to expect.
