(<!DOCTYPE html>): The <!DOCTYPE html> declaration at the very
top of an HTML file informs the browser that the document is HTML5. This helps the browser render the
page in standards-compliant mode, avoiding quirks mode . It is not an HTML tag, but a crucial
preamble.
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8″>
<title>My Page</title>
</head>
<body>
