Q8. What is Doctype in HTML5? What is the requirement of using it?
Answer:
Declaration of the doctype is the very first thing in your HTML document even before the <html> tag.
Declaring Doctype tells the browser to use "standard" mode to render the document.
Also by looking at syntax of doctype declaration browser knows in which HTML version page is written.
