Launch VS Code.
On VS Code, go to File >> New File.
Copy and paste this code:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />
<title>Untitled Document</title>
</head>
<body>
</body>
</html>
Save your new file as .html in the folder for your project. If this is the first file of your project, it probably should be named index.html.
