Some elements don't need close tags, or even open tags. Unless you're
using XHTML you don't need them and indeed for the case of void tags
(e.g. <br>, <img>) you must not include the close tags.
A minimal HTML file might look like this:
<!DOCTYPE html>
<html lang=en><meta charset=utf-8><title>Minimal HTML file</title>
<main><h1>Minimal HTML file</h1>This is a minimal HTML file.</main>
which would be parsed into this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Minimal HTML file</title>
</head>
<body>
<main>
<h1>Minimal HTML file</h1>
This is a minimal HTML file.
</main>
</body>
</html>
Adding in the omitted <head>, </head>, <body>, </body>, and </html>
would make no difference and there's no particular reason to recommend
doing so as far as I'm aware.
