<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML> <HEAD>heading material</HEAD>
<BODY>body material</BODY> </HTML>
The first line identifies the version of HTML adhered to in the file. If this line is missing version 2.0 is assumed.
Some of these tags are not checked for by some browsers. Note that most tags occur in pairs, with a slash in the closing tag. The words HTML, HEAD, and BODY may be upper-case or lower-case.
There are several items that can go in the heading, but typically the only item is the title, which is of the form
<TITLE>Jim's Home Page</TITLE>
The title appears in the top of the browser window.
