Answer:
Assuming you mean the HTML5 head tag, then this may work for you:
<!DOCTYPE HTML>
<html lang="en">
<head>
<title>My Very Awesome Website</title>
<link href="./css/main.css" rel="stylesheet" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<h1>Hey look</h1>
<p>This is my awesome website!</p>
<h3>Note</h3>
<p>This website is supposed to be 100% awesome!</p>
</body>
</html>
