using HTML.

You can put lots of text here if you want.
We could go on and on with fake text for you
to read, but let's get back to the topic.

In the case of XHTML, which is a form of HTML that is based upon the syntax rules of
XML, we really don't see many major changes yet in our example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>
Hello XHTML World
</title>
<!-- Simple hello world in XHTML 1.0 strict example -->
</head>
<body>
<h1>
Welcome to the World of XHTML
</h1>

<p>
XHTML
<em>
really
</em>
isn't so hard either!
</p>

Soon you will
♥
using XHTML too.

There are some differences between XHTML
and HTML but with some precise markup you'll
see such differences are easily addressed.

The preceding examples use some of the most common elements used in (X)HTML
documents, including:
• The
<!DOCTYPE>
statement, which indicates the particular version of HTML
or XHTML being used in the document. The first example uses the strict 4.01
specification, the second uses a reduced form for HTML5 the meaning of which
will be explained a bit later on, and the final example uses the XHTML 1.0 strict
specification.
• The
<html>
,
<head>
, and
<body>
tag pairs are used to specify the general structure
of the document. The required inclusion of the
xmlns
attribute in the
<html>
tag is
a small difference required by XHTML.
• The
<meta>
tag used in the examples indicates the MIME type of the document and
the character set in use. Notice that in the XHTML example, the element has a trailing
slash to indicate that it is an empty element.
• The
<title>
and
</title>
tag pair specifies the title of the document, which
generally appears in the title bar of the Web browser.
• A comment is specified by
<!-- -->
, allowing page authors to provide notes for
future reference.
