HTML is set of mark up symbols and codes which are inserted in a file intended to display on world wide web browser page , the mark up tells the web browser how to display a web pages words and images for the user, every individual mark up code is referred to as an element. HTML is a formal recommendation by the World Wide Web consortium and is generally attached to the major browsers. The launching of the ISO took place in 1986. This ISO standard was named as ISO 8879, the creation of this standard was to make displaying the differences
HTML vs. XHTML is a hot debate and many beginners ask about the difference between both hypertext markup languages. For the expert users the answer is very simple to understand and but the novice users might remain confused. You may find many novice users in the learning phase to ask such questions as various blogs, forums etc. They still have to build their own concepts and gain experience.
For a novice user or learner of HTML or XHTML the answer is very simple that XHTML is only for the experts and the new users or beginner should not jump
Markup languages are many but few of them are most in use. If you want to learn about such languages or want to know the difference between them then this article is the right place for you. Through this short note you will be able to learn the difference between XHTML and HTML. These both are language used to develop web pages. People think these both are totally different languages then each other, but that’s not correct all time.
XHTML is not much different than HTML version 4.01. If you are aware of coding in 4.01 version then you can
The accesskey attribute sounds like a great idea at first. Being able to attach a keyboard shortcut to elements in an HTML document allows users to quickly jump to different parts of the page or trigger functionality without having to use a mouse.
The problem, as has been stated by Derek Featherstone in More reasons why we don’t use accesskeys, John Foliot in Using Accesskeys - Is it worth it?, and Jukka Korpela in Using accesskey attribute in HTML forms and links, to name a few, is that most current web browsers do not prevent shortcuts assigned
"HTML5 (also sometimes referred to as Web Applications 1.0) is a technology developed by the WHATWG, an open community started by three of the four major browser vendors: Mozilla, Opera, and Apple. HTML5 is not so much a replacement for HTML 4.01 or XHTML 1.0 as it is an upgrade or evolution. It aims for backwards compatibility, tries to remove undefined behavior in HTML 4.01 by defining it, and looks at the various browsers’ tag-soup parsing behavior to try to define the best solution that doesn’t break the web. At the same time, it adds sorely
Nobody's perfect, but when you're a web developer it sometimes seems that the whole world expects you to be. "DOCTYPE confusion.Completely missing, incorrect, or in the wrong place. I have seen HTML 4.0 Transitional used in documents containing XHTML markup as well as in documents, DOCTYPE declarations appearing after the opening tag, and incomplete DOCTYPES.
Why? Two reasons. First, it’s required, as stated in the W3C HTML 4.01 spec as well as in the W3C XHTML 1.0 spec. Second, modern web browsers use the specified DOCTYPE to decide which
"So What is a DTD?
The tags in the HTML language must be defined somewhere, right? They are defined in the DTD, which stands for Document Type Definition. In a DTD for HTML, all the HTML tags are defined. Everything is defined in the DTD -- the tags, the attributes, the possible values they can hold. Think of the DTD as the HTML tag dictionary: it lists all the tags, what they mean, and how they relate to each other.
Also, there are different DTDs because there are different versions of HTML:
HTML 4.01 Strict
HTML 4.01 Transitional
XHTML
XHTML is not very different from the HTML 4.01 standard. So, bringing your code up to the 4.01 standard is a good start. Our complete HTML 4.01 reference can help you with that.
In addition, you should start NOW to write your HTML code in lowercase letters, and NEVER skip ending tags (like </p>).
Happy coding!
The Most Important Differences:
XHTML elements must be properly nested
XHTML elements must always be closed
XHTML elements must be in lowercase
XHTML documents must have one root element

HTML is very easy to use; it was designed that way. You don't have to be a programmer to use it. If you can edit a text file, then you can write HTML (and if you can write email, you can edit a text file). If you tried to learn before and couldn't, then someone wasn't telling you the right things.
This tutorial will explain the structure of HTML quickly and clearly, and show you through examples the practical things you need to know, so you can be making your own pages soon (like, this afternoon). The whole tutorial is about 14 printed pages, but you
In a sense, nobody is in charge of the web. The web is an open standard, with no restrictions on who can post content, or what that content should be about. The web belongs to everybody, and so it belongs to nobody. The openness and decentralization of the web is one of its greatest strengths. But it wouldn't work at all without some sort of standard way of encoding the information. That's where the World Wide Web consortium (W3C) comes in.
The W3C is an international, vendor-neutral group that determines the protocols and standards for the web. They
This is an introduction of the very basics of HyperText Mark-up Language. H-T-M-L are initials that stand for HyperText Markup Language (computer people love initials and acronyms -- you'll be talking acronyms ASAP). Let me break it down for you:
# Hyper is the opposite of linear. It used to be that computer programs had to move in a linear fashion. This before this, this before this, and so on. HTML does not hold to that pattern and allows the person viewing the World Wide Web page to go anywhere, any time they want.
# Text is what you will use.
In 1986, a new ISO standard (ISO 8879) was released which aimed to make platform and display differences irrelevant to the delivery and rendering of documents. This standard detailed the language called the Standard Generalized Markup Language (SGML.)
Tim Berners-Lee and the Genesis of the WWW
In 1989, Tim Berners-Lee created a proposal for a hypertext document system to be used within the CERN community. Although based in Switzerland, CERN members were scattered throughout the globe and project turnover was often high. Collaboration over long
When we hear the word XHTML we automatically think of the CSS interface and the text language of the internet or World Wide Web. Recently we got use to using this tool of script to write into the CSS scripting to perform our many tasks and designs on web pages and browsers. But why the change over from the old to the new XHTML 2? Well it has a large part to do with the introduction of the new Microsoft software’s and internet Explorer 7 releasement. The W3C works on making sure that all software’s are compatible in use with each other so they can
Cleaning the code in the edited content is one important new addition in KTML 4. You have the option to choose from cleaning only the Word tags, only the CSS formatting, or cleaning all the formatting tags inside the code. Saving the code as XHTML compliant is also one of KTML's possibilities.
To make this completely possible, you must however install and configure the HTML Tidy utility:
1.
Download and install the HTML Tidy version suited for your particular server configuration. You need a version released in 2005 or higher.
2.

Features:
* Suggests fixes and improvements for common errors found in HTML, XHTML and XML documents.
* Check multiple documents through the Batch Action Wizard.
* Ability to read settings from a default Tidy config file [new].
* Convert documents to XHTML and XML formats.
* Upgrade FONT tags to style sheets.
* Remove optional end tags.
* Indent / beautify tags, attributes and/or content.
* Change tags and/or attributes to uppercase or lowercase.
* Strip surplus tags in HTML documents generated using Word.
* Check for accessibility.

To use the W3C's validation services to validate HTML code the DOCTYPE declaration is required. This goes at the very top of your HTML coding. To learn more about where the DOCTYPE declaration goes, see our HTML Document Structure article. The DOCTYPE declaration sets what HTML specification standard the document is coded for so the browsers and validators know how to process HTML code.
Leave the following items at their default:
* Character Encoding
Will check that you included the character encoding meta tag and if it is coded correctly.
* Document

XHTML is the standard markup language for web documents and the successor to HTML 4. A mixture of classic (HTML) and cutting–edge (XML), this hybrid language looks and works much like HTML but is based on XML, the web’s “super” markup language, and brings web pages many of XML’s benefits, as enumerated by the Online Style Guide of the Branch Libraries of The New York Public Library.

Why bother with keeping your code up to date with what the W3C recommends? Don't! Please, put up bleeding-edge Web pages that take advantage of bugs in browsers. Contribute to the working anarchy we fondly call the Internet.
While I do not enjoy stylistic exploits that unknowingly (or even knowingly) create security holes, exploits that contribute to the art world -- even if they only last until everybody updates their browser to the next version -- are wonderful.
Pushing the boundaries of design is part of the Zen experience of the Web. However,
Document types have been a part of HTML for a long time, but few developers use them even though they are required in order to be compliant. XHTML is no different, and an additional XML tag can, and usually should, be used. Section 3.1.1 "Strictly Conforming Documents", of the XHTML 1.0 specification describes this in detail, so read the chapter for a complete overview.
Usually, your document type declaration will look something like this:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
It seems like the eternal question amongst web developers: HTML or XHTML? Wherever I look there seems to be posts in forums raising the question, web developers asking me or other people write blog posts about what they believe is the right way to go. I’m not writing this post to tell you what the ultimate choice is, but rather to inform you about the consequences of what you choose. So, let’s take it from the top:

I’ve finally enabled a subset of HTML in my comments. In doing so, I had several requirements that needed to be fulfilled:
1. Entered markup must be valid to XHTML strict, to stop comments form breaking validation and keep things nice and tidy.
2. No presentational markup! I want to maintain control over how things look via my stylesheets—comments posted should only be able to use structural HTML elements.
3. Attributes should be restricted to those that add semantic meaning. Javascript event attributes and CSS related attributes should not be
As you know, XML is case sensitive: A tag defined in all uppercase letters needs to be written in all uppercase letters; a tag defined all in lowercase needs to be written all in lowercase. In XHTML, all tags are defined in lowercase. When writing XHTML 1.0 documents refer to the HTML 4.01 specification for information about specific tags and arguments, specificaly the "Index of Elements" and the "Index of Attributes." Any examples you see will remain nearly the same when converted to XHTML, except that you will need convert everything to
The evolution of HTML has essentially stopped. Instead, HTML is being replaced by a new language, called XHTML. XHTML is in many ways similar to HTML, but is designed to work with the new eXtensible Markup Language, or XML, that will soon serve as the core language for designing all sorts of new Web applications, in which XHTML will be only one of many "languages." But, XHTML is designed to work with these other language, so that different documents, in different languages, can be easily mixed together.
For this to work, the rules for writing HTML
This is a well-discussed and very important topic. Personally, presently I write XHTML for my web interface code, but lately I’ve started to stagger in my standpoint. For normal general web page design, what’s the gain? If you don’t extend the code with namespaces, use MathML, have your own DTDs and so on, why would you want to use XHTML?
Many people answer that question with: “It makes me write leaner code, code that has to validate and be more semantic correct”. Martin 0 wrote a post 0 recently why he uses XHTML (unfortunately, it’s in
Still writing your documents in HTML? If you are, you're not complying with current standards. On January 26, 2000, XHTML 1.0 became a recommendation by the World Wide Web Consortium (W3C). HTML, according to the W3C, is no longer the Web markup standard. Instead, XHTML 1.0 has replaced our old favorite, marking up the dawn of a new and exciting time in communications technology.
So what exactly is XHTML 1.0 and what does it mean to the Web developer? I'll start with the W3C's description: XHTML 1.0 is a reformulation of HTML as an XML application.
XHTML is a combination of HTML and XML (EXtensible Markup Language).
XHTML consists of all the elements in HTML 4.01 combined with the syntax of XML.
Why XHTML?
We have reached a point where many pages on the WWW contain "bad" HTML.
The following HTML code will work fine if you view it in a browser, even if it does not follow the HTML rules:

XHTML is a markup language written in XML; therefore, it is an XML application.

The XHTML 2 specification isn't finished, but it already has many advantages over XHTML 1, including a greater structural richness that will make it more viable than its predecessor as an editorial format to serve as the central schema for a single-source publishing system. Without waiting for browser support of the new user interface features in XHTML 2, people who do large- or small-scale publishing can start to use these new features now.
About a year ago, an industry standards group asked me to do a presentation on how XHTML 2 might be useful to
The RELAX NG kind, and maybe the XSD kind.
I wanted to use Emacs+nxml to create some XHTML 2 documents, so I went looking for an XHTML 2 schema. The latest Working Draft says that it "includes an early implementation of XHTML 2.0 in RELAX NG, but does not include the implementations in DTD or XML Schema form. Those will be included in subsequent versions, once the content of this language stabilizes." This schema's location is not obvious, but a few web searches turned up a pointer to the ZIP archive version of the Working Draft mentioned in the

I still believe that we don't need to embed RDF directly into our web pages because many web sites are dynamic now. As such, if one accesses the page as a human, you get data formatted for human consumption through a browser; if you access the page as a webbot, by attaching /rdf to the end of the document, the same data is formatted for mechanical consumption. No need to clutter up web pages, or make page creation or generation that much harder.
I think that XHTML 2 will be used for more than delivery of content to browsers, adding a lot of value to
One thing I like about the upcoming XHTML 2 is the way it handles headings. Anyone who ever touched HTML knows a heading is written as <h1>...</h1>, <h2>...</h2> and so on. This goes down to "h6" and indicates the level (importance) of the heading. It is always good to start with h1, and then go down, so that you won't have a document with an h3 where there is no h2, and so on (ISO-HTML even makes this mandatory).
If you ever need more than 6 levels of headings, you've hit a limit in HTML. But there was another problem as
Abstract
XHTML 2 is a general-purpose markup language designed for representing documents for a wide range of purposes across the World Wide Web. To this end it does not attempt to be all things to all people, supplying every possible markup idiom, but to supply a generally useful set of elements.

The discussion of XHTML versus HTML has popped up again, and until now I've managed to resist the urge to throw in my 2¢. Well, no longer will I sit on the side line while the same arguments get rehashed again and again, which will not get us anywhere. In this article, which I originally published in my blog, I'll attempt to answer this question: does the future of the Internet lie with HTML or XHTML?
Firstly, I'm just going to set a few ground rules. This is not going to be another version of XHTML as text/html is considered harmful or there are no
