I cannot wrap my head around some of the basic structural <tags> being "optional," but you do have cloisng </html> so you definitely need to have opening <HTML> tag, which you do not have
<!doctype html>
[B]<html>[/B]
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>
</head>
<body>
</body>
[B]</html>[/B]
