Where is

Declaration of a Doctype: A DOCTYPE declaration appears at the top of a web page before all other elements. According to the HTML specification or standards, every HTML document requires a document type declaration to ensure that the pages are displayed in the way they are intended to be displayed.

How does doctype relate to page validation?

Per HTML and XHTML standards, a DOCTYPE (short for “document type declaration”) informs the validator which version of (X)HTML you're using, and must appear at the very top of every web page. DOCTYPEs are a key component of compliant web pages: your markup and CSS won't validate without them.

When a Web browser encounters a doctype tag it processes the page in?

When a Web browser encounters a DOCTYPE tag, it processes the page in standards mode. When it doesn't encounter the DOCTYPE tag, it assumes that there is something quirky about the page, and processes the page in quirks mode.

What information does

The DOCTYPE declaration is an instruction to the web browser about what version of HTML the page is written in. This ensures that the web page is parsed the same way by different web browsers. In HTML 4.01, the DOCTYPE declaration refers to a document type definition (DTD).

Is HTML document correct?

Validation. As I mentioned earlier, the doctype is also used by validators, which you will learn more about later in this article series. For now, all you need to know is that a validator is used to check that the syntax of your HTML document is correct and does not contain any mistakes.

Why doctype is used in HTML?

Doctype stands for Document Type Declaration. It informs the web browser about the type and version of HTML used in building the web document. This helps the browser to handle and load it properly. While the HTML syntax for this statement is somewhat simple, you must note each version of HTML has its own rules.
