HTML and CSS Reference
In-Depth Information
<p> Soon you will &hearts; using HTML. </p>
<p> 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. </p>
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"
<html xmlns="">
<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 -->
<h1> Welcome to the World of XHTML </h1>
<hr />
<p> XHTML <em> really </em> isn't so hard either! </p>
<p> Soon you will &hearts; using XHTML too. </p>
<p> There are some differences between XHTML
and HTML but with some precise markup you'll
see such differences are easily addressed. </p>
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
• 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.
