HTML Doctypes

HTMLWeb DevelopmentFront End Technology

Whenever you create an HTML document, the doctype is the first thing placed in the document.

It conveys the web browser about the version of the HTML, this page is written on. It is not casesensitive.

Let us see an example displaying DOCTYPE on the top −

Example

 Live Demo

<!DOCTYPE html>
<html>
<head>
<title>Document Title comes here</title>
</head>
<body>
<h1>
   Demo Heading
</h1>

</body>
</html>

Output

Now let us see some of the declarations for doctype −
