That's not a "program". The web browser is simply displaying what is essentially a text file.
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
Still not a program, but it is HTML. That's one of the simplest HTML sites you can make. Teaching people how to properly make those tags and nest them, that's the simplest HTML introduction you can do.
HTML is not a programming language. It's a formatting language. It's in the name. It's a markup language.
