Lesson 8_Tags

Heading tags
Heading in html can be defined using this tag.There are <h1> to <h6> heading tags.It is a container tag.
The following example will demonstrate the heading tags

<html>
<body>

<h1>This is heading 1</h1>
<h2>This is heading 2</h2>
<h3>This is heading 3</h3>
<h4>This is heading 4</h4>
<h5>This is heading 5</h5>
<h6>This is heading 6</h6>

</body>
</html>

Ouput

This is heading 1

This is heading 2

This is heading 3

This is heading 4

This is heading 5

This is heading 6

Paragraph tag
HTML paragraphs are defined with the <p> tag.

example

<html>
<body>

<p>This is paragraph 1.</p>
<p>This is paragraph 2.</p>
<p>This is paragraph 3.</p>

</body>
</html>

Output

This is paragraph 1.

This is paragraph 2.

This is paragraph 3.

Lesson 7

Basic structure of HTML

All html pages will start with the tag <html> and end with </html>.All other tags are inside these tags.
Every thing that we want to see will be write inside <body>....</body> tag.
The common structure is as follows

<html>
<body>
Body of your page
</body>
</html>

This structure must have to be follow for writing html codes

Lesson 6

HTML tags
Tags can be either container tag or empty tag.
Container tags are those tags which have opening and closing tags.
eg:-
<html>....</html>
<body>....</body>
<h2>....</h2>
etc
Empty tag is a singular tag(not in a pair)
eg:-
<br>
<img>
etc

Now we can discuss the different tags available on html

Lesson 5

Getting start of writing HTML pages

For writing html codes you need not need a special editor. It can be write simply on notepad(plain text editor).However we can also make use of differen editors like Dreamweaver and Visual Studio etc.

Let us start with a simple example

First take note pad and write the following code
<html>
<head>
</head>
<body>
Welcome to HTML
</body>
</html>

After completing the code save the notepad with your desired file name with either one of the extension .html,.htm,.mth(no difference between these).

Here we save the page as eg.html

Now you open any browser and from the file menu you just open the page that you are saved in your computer.Now you can see the output as follows

This is how we write html codes and generate web pages.This procedure will be used through out the html session

Lesson4

HTML Tags

HTML markup tags are usually called HTML tags

HTML tags are keywords surrounded by angle brackets like <html>
HTML tags normally come in pairs like <b> and </b>
The first tag in a pair is the start tag, the second tag is the end tag
Start and end tags are also called opening tags and closing tags

There are lot of tags are available in HTML.We discuss these tags in future

Lesson3

Versions Of HTML

HTML 2.0

HTML 2.0 was developed by the Internet Engineering Task Force HTML Working Group in 1996.
HTML 2.0 is an outdated version of HTML. For a Web developer there is no need to study the HTML 2.0 standard.

HTML 3.2

HTML 3.2 became a W3C Recommendation 14. January 1997. HTML 3.2 added new features such as fonts, tables, applets, superscripts, subscripts and more, to the existing HTML 2.0 standard.
One of the elements added to the HTML 3.2 standard, was the <font> tag. This tag introduced unnecessary complexity to the important task of separating HTML content (text) from its presentation (style). The <font> tag became deprecated in HTML 4.0.

HTML 4.0

HTML 4.0 became a W3C Recommendation 18. December 1997. A second release was issued on 24. April 1998 with only some editorial corrections.
The most important feature of HTML 4.0 was the introduction of style sheets (CSS).

HTML 4.01

HTML 4.01 became a W3C Recommendation 24. December 1999.
HTML 4.01 was a minor update of corrections and bug-fixes from HTML 4.0.

XHTML 1.0

XHTML 1.0 reformulates HTML 4.01 in XML.

HTML 5

HTML 5 improves interoperability, and reduces development costs, by making precise rules on how to handle all HTML elements, and how to recover from errors.
Some of the new features in HTML 5 are functions for embedding audio, video, graphics, client-side data storage, and interactive documents.
HTML 5 also contains new elements like <nav>, <header>, <footer>, and <figure>.
The HTML 5 working group includes AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera, and many hundred other vendors.

Specification
HTML 3.2	14. January 1997
HTML 4.0	24. April 1998
HTML 4.01	24. December 1999
HTML 5	19. October 2010 (latest draft)

Lesson 2

History of HTML

First specifications

The first publicly available description of HTML was a document called "HTML Tags", first mentioned on the Internet by Berners-Lee in late 1991. It describes 20 elements comprising the initial, relatively simple design of HTML. Except for the hyperlink tag, these were strongly influenced by SGMLguid, an in-house SGML based documentation format at CERN. Thirteen of these elements still exist in HTML 4.
Hypertext markup language is a markup language that web browsers use to interpret and compose text, images and other material into visual or audible web pages. Default characteristics for every item of HTML markup are defined in the browser, and these characteristics can be altered or enhanced by the web page designer's additional use of css Many of the text elements are found in the 1988 ISO technical report TR 9537 Techniques for using SGML, which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS (Compatible Time-Sharing System) operating system: these formatting commands were derived from the commands used by typesetters to manually format documents. However, the SGML concept of generalized markup is based on elements (nested annotated ranges with attributes) rather than merely print effects, with also the separation of structure and processing; HTML has been progressively moved in this direction with CSS.
Berners-Lee considered HTML to be an application of SGML. It was formally defined as such by the Internet Engineering Task Force (IETF) with the mid-1993 publication of the first proposal for an HTML specification: "Hypertext Markup Language (HTML)" Internet-Draft by Berners-Lee and Dan Connolly, which included an SGML Document Type Definition to define the grammar.The draft expired after six months, but was notable for its acknowledgement of the NCSA Mosaic browser's custom tag for embedding in-line images, reflecting the IETF's philosophy of basing standards on successful prototypes. Similarly, Dave Raggett's competing Internet-Draft, "HTML+ (Hypertext Markup Format)", from late 1993, suggested standardizing already-implemented features like tables and fill-out forms.
After the HTML and HTML+ drafts expired in early 1994, the IETF created an HTML Working Group, which in 1995 completed "HTML 2.0", the first HTML specification intended to be treated as a standard against which future implementations should be based.Published as Request for Comments 1866, HTML 2.0 included ideas from the HTML and HTML+ drafts. The 2.0 designation was intended to distinguish the new edition from previous drafts.
Further development under the auspices of the IETF was stalled by competing interests. Since 1996, the HTML specifications have been maintained, with input from commercial software vendors, by the World Wide Web Consortium (W3C). However, in 2000, HTML also became an international standard (ISOIEC 15445:2000). The last HTML specification published by the W3C is the HTML 4.01 Recommendation, published in late 1999. Its issues and errors were last acknowledged by errata published in 2001.

Lesson 2

History of HTML

Origins

Add caption

In 1980, physicist Tim Berners-Lee, who was a contractor at CERN, proposed and prototyped ENQUIRE, a system for CERN researchers to use and share documents. In 1989, Berners-Lee wrote a memo proposing an Internet-based hypertext system. Berners-Lee specified HTML and wrote the browser and server software in the last part of 1990. In that year, Berners-Lee and CERN data systems engineer Robert Cailliau collaborated on a joint request for funding, but the project was not formally adopted by CERN. In his personal notefrom 1990 he lists"some of the many areas in which hypertext is used" and puts an encyclopedia first

Lesson 1

HTML

With HTML you can create your own Web site.
This tutorial teaches you everything about HTML.

What is HTML

HTML is not a programming language, it is a markup language
HTML is HyperTextMarkupLanguage
Hyper Text means text display, ie displaying the text in your website.
Markup means collection of symbols and tags .
Thus HTML is a collection of symbols and tags that used to design the display of text in your website
