your webpage should be displayed in.
<!doctype html> used in html5
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
HTML4.01 Strict DOCTYPE removes all the deprecated tags from the specificstion.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
HTML4.01 Transitional DTD is the most popular one.
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.
DOCTYPE stands for Document Type Definition is a tag in a web page. It tells the browser how to render the page in standards compliant mode.
