Introduction to HTML
HTML Document Structure in Depth

The <!DOCTYPE> Declaration
 At their beginning HTML documents must have a
document type declaration
 It tells the Web browsers how to handle the HTML
data
 Possible versions: HTML 2.0, HTML 3.2, HTML 4.01,
XHTML 1.0, XHTML 1.1, …
 Example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 See http://www.w3.org/QA/2002/04/Web-Quality for a list
of possible doctypes
22

HTML vs. XHTML
 XHTML is more strict then HTML
 All tags must be properly nested (HTML allows
<b><i>text</b></i>)
 Tags and attribute names must be in lowercase
 Attribute values must be in " " (HTML allows ' ')
 All tags must be closed (<br/>, <img/>) while
HTML allows <br> and <img>
 XHTML allows only one root <html> element
(HTML allows more than one)
23

XHTML vs. HTML (2)
 Many element attributes
are deprecated in
XHTML, most are moved to CSS
 Attribute minimization is forbidden, e.g.
<input type="checkbox" checked>

<input type="checkbox" checked="checked" />

 Note: Web browsers load XHTML faster than
HTML and valid code faster than invalid!

24

HTML Structure
 HTML is comprised of elements called “tags”
 Begins with <html> and ends with </html>
 When writing XHTML, must define a namespace
<html xmlns="http://www.w3.org/1999/xhtml">

 Tags are nested one inside another:
<html> <head></head> <body></body> </html>
 Tags have attributes:
<img src="logo.jpg" alt="logo" />
 HTML describes structure using two main sections:
<head> and <body>
25

The <head> Section
 Contains information that doesn’t show
directly on the viewable page
 Starts after the <!doctype> declaration

 Begins with <head> and ends with </head>

 Contains mandatory single <title> tag

 Can contain multiple nested tags, e. g.:
 <meta>
 <script>
 <style>
 <!– comments -->
26

<head> Section: <title> tag
 Title should be placed between <head> and
</head> tags
<title>Telerik Academy – Winter Season 2009/2010
</title>

 Used to specify a title to the Web page window
 Search engines and people rely on titles
27

<head> Section: <meta>
 Meta tags additionally
describe the content
contained within the page
<meta name="description" content="HTML
tutorial">

<meta name="keywords" content="html, web
design, styles">

<meta name="author" content="Chris Brewer">

<meta http-equiv="refresh" content="5;
url=http://www.telerik.com">

28

<head> Section: <script>
 The <script> </script> tag is used to
embed scripts into an HTML document
 Script are executed in the client's Web browser
 Scripts can live in the <head> and in the <body>
sections
 Supported client-side scripting languages:
 JavaScript (it is not Java!)
 VBScript
 JScript
29

The <script> Tag – Example
<html> scripts-example.html
<head>
<title>JavaScript Example</title>
<script type="text/javascript">
function sayHello() {
document.write(
"<p><b>Hello World!</b>");
}
</script>
</head>
<body>
<script type=
"text/javascript">
sayHello();
</script>
</body>
</html>
30

<head> Section: <style>
 The <style> </style> tag embeds formatting
information (CSS styles) into a HTML page
<html> style-example.html
<head>
<style type="text/css">
p { font-size: 12pt; line-height: 12pt }
p:first-letter { font-size: 200%; float: left }
span { text-transform: uppercase }
</style>
</head>
<body>
<p>Styles demo.</p>
<span>Test uppercase</span>.
</body>
</html>
32

Embedding CSS Styles
Live Demo

Comments:  Tag
 Comments can exist anywhere between the
<html></html> tags
 Comments start with 

<!–- BASD Logo (it is a GIF file with
transparent background) -->
<img src="logo.gif" alt="BASD Logo">
<!–- Hyperlink to BASD official Web site -->
<a href="http://www.devbg.org/">BASD Home</a>
<!–- Show the news table -->
<table class="newstable">
...

34

<body> Section: Introduction
 The <body> section describes the viewable
portion of the page
 Starts after the <head> </head> section

 Begins with <body> and ends with </body>

<html>
<head><title>Test page</title></head>
<body>
This is the Web page body!
</body>
</html>

35

<body> Section: Attributes
 The <body> tag has the following attributes:
background Background image file ="URL"
bgcolor Background color ="color"
text Default text color ="color"
link Hyperlink color ="color"
vlink Visited hyperlink color ="color"

 Example:
<body background="texture.gif" text="#238E23">

* For color codes, see www.webreference.com/html/tools/colorizer/
36

Text Styling without CSS
 Text can be formatted  Different styles of
as headings or regular heading are
paragraph text available:
 Use these consistently! <h1></h1> Heading 1
 <p></p> by default <h2></h2> Heading 2
doubles the spaces <h3></h3> Heading 3
after each paragraph <h4></h4> Heading 4
<h5></h5> Heading 5
 <br /> is weird: the <h6></h6> Heading 6
trailing “/” makes it <p></p> Paragraph

XHTML compliant <br /> Line break

37

Text Formatting
 Text formatting tags modify the text between
the opening tag and the closing tag
 Ex. <b>Hello</b> makes “Hello” bold
<b></b> bold
<i></i> italicized
<u></u> underlined
<sup></sup> Samplesuperscript
<sub></sub> Samplesubscript
<strong></strong> strong
<em></em> emphasized
<pre></pre> Preformatted text
<blockquote></blockquote> Quoted text block
<del></del> Deleted text – strike through
38

Text Formatting – Example
text-formatting.html
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
<html>
<head>
<title>Svetlin Nakov</title>
</head>
<body bgcolor="black" text="white" link="red" vlink="blue">

weight:bold">only a test</span>.</p>
67
