Here is how to specify the document type for some HTML5 code.

1

Insert this code

Insert <!DOCTYPE html> at the first line of the HTML code.

Example:

<!DOCTYPE html>
<html>
	<head>
		...
	</head>
	<body>
		...
	</body>
</html>

(!) — If you don't specify the document type, some web browsers may render your page in "backwards compatibility mode" (also known as "quirks mode"), so be sure to specify it as shown above.
Be sure to have nothing (even a simple comment) before the doctype declaration. In this case, some browsers may ignore it!
