W3C VALIDATION

W3C basically it stand World Wide Web Consortium allows users to check HTML documents for conformance to HTML (hyper text markup language) or XHTML. It also provides a quick method for web page authors to check their posted pages for mark-up errors.

Most Web documents are written using markup languages, such as HTML or XHTML. These languages are defined by technical specifications, which usually include a machine-readable formal grammar (and vocabulary). The act of checking a document against these constraints is called validation, and this is what the Markup Validator does.

W3C home page for the XHTML2 Working group, which was chartered in March 2007. XHTML2 Working group is to fulfill the promise of XML for applying XHTML to a wide variety of platforms with proper attention paid to internationalization, accessibility, a device –independence, usability and document structuring. The group will provide an essential piece for supporting rich Web content that combines XHTML with other W3C work on areas such as math, scalable vector graphic, synchronized multimedia, and forms, in cooperation with other Working Groups.

W3C produces what are known as “Recommendations”. These are specifications, developed by W3C working groups, and then reviewed by Members of the Consortium. A W3C Recommendation indicates that consensus has been reached among the Consortium Members that a specification is appropriate for widespread use.
There are also many excellent tools developed outside W3C to help improve the quality of Web pages.

HTML tidy, originally developed at W3C, is a program that can help automatically clean up HTML pages.
Validome offer a very reliable validator for HTML, XHTML and WML, in different languages.
The WDG HTML validator is another excellent online validation service.
Site Valet by Nick Kew is a comprehensive set of Quality Assurance tools for checking and monitoring your web sites.

The W3C also hosts a number of other Open Source software projects. In addition to this validator, the W3C is offering a number of other tools to help you check other types of documents (CSS, RDF, P3P…), find broken links in your Web pages, and so on.

Validation Web documents is an important step which dramatically help improving and ensuring their quality, and it can save a lot of time and money (read more on why validating matters). Validation is, however, neither a full quality check, nor is it strictly equivalent to checking for conformance to the specification.

This validator can process documents written in most markup languages. Supported documents types include the HTML (through HTML 4.01) and XHTML (1.0 and 1.1) family. The Markup Validator can also validate web documents written with an SGML or XML DTD, provided they use a proper document type declaration.

This validator is also “An HTML validating system conforming to International Standard ISO/IEC 15445—Hypertext Markup Language, and International Standard ISO 8879—Standard Generalized Markup Language (SGML)” – which basically means that in addition to W3C recommendations, it can validated according to these ISO standard.

Web Server in Linux

A web server provides ability or takes advantage of web based applications. In simple it is where a website physically resides. The softwares required are redhat, suse, fedora etc. Many versions of redhat such as 7.0, 8.0 etc can also be used. The webpages are directly served from the directory as configured by the document root directive. The apache may be configured to run as a host of a single website or it can also be configured to run multiple domains. This can be achieved in two ways such as Virtual hosts and multiple IP based virtual hosts.

First change the default value for server name. It is prudent to limit apache’s view only to necessary directories. It can be done by not granting access to everything but only grant access to necessary directories. The Apache web server allows to congfigure a single computer to represent multiple websites. This can be done in two ways such as name based virtual host and IP based virtual host. Once you do this your default system domain will stop working and the default domain must now be considered as virtual domain. There must be a limit on maximum number of clients who can simultaneously connect. If this limit is exceeded then the clients will be locked out There is no need to grant a shell account which allows only the user more potential security holes it can be included in the file when creating the user . The Chroot blind provides an extra security also. You can use a single Linux server to forward requests to a cluster of servers.

HTML

Html: Hyper Text Markup language

What actually an HTML means??... Who developed this language for the first time? Where is it been used??... In what way does it help an web developer??... Answers to these questions will end here.

Definition:
HTML is a MarkUp language used by web browsers in creating a website.

HTML helps you to create your own website. It is not a programming language as it name itself tells you its“Markup”… A Markup language consists of tags which are basically used as commands in publishing a web site.
The structured documents are created using tags, which are semantics used in formatting text such as headings, paragraphs, titles, header, images and so on. I have been speaking about tags what actually does it mean and in what format do they need to be written??..

HTML Tags:

HTML tags are keywords surrounded by angle brackets like . There is a format involved in using these tags, they come in pairs like and . Each is respectively called as start tag and end tag.

You were introduced to the world of HTML. Lets go in depth, starting of wit its origin.

History

In 1989, Physicist Tim Berners-Lee who was working as a contractor in CERN 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.

Tim Berners-Lee

In the late year, along with Robert Cailliau made a joint request for funding this project to come alive but the project was not formally adopted by CERN. Now HTML is been standardized to many versions such as HTML 1.0, HTML 2.0 in the consequent years .

Now we shall study HTML with an example.

My First Heading

My first paragraph.

What all these tags tell you all about its start of an heading or paragraph or title. Once we have started with any tag it has to compulsorily end.

The element defines the body of the HTML document
The element has a start tag and an end tag
The element content is another HTML element (a paragraph). Similarly the tags refer.

You could think how actually a link is inserted in the content of a web page, its using attributes.

HTML Attributes

Attributes provide additional information about HTML elements.

HTML elements can have attributes
Attributes provide additional information about the element
Attributes are always specified in the start tag
Attributes come in name/value pairs like: name="value"

The link address is provided as an attribute:
This is a link

So what will the above statement look like on the web page??
Try yourself here.

Similarly formatting, styles, images forms, lists, colors, tables are done using tags.

Getting started with HTML

To get started with HTML what all you need is editors like front page or Dreamweaver. Once you have finished with editing you need to save the file having an extension either .htm or .html.

Publishing the content onto the site

This requires a protocol for the delivery of the HTML, ie., HTTP.

CSS TEMPLATES(CASCAD STYLE SHEET)

A CSS (CASCADING STYLE SHEET) is a file separates the websites from the (X) HTML content's file.
The (X) HTML file arrange the contains but for presentation (Border, style, color, table etc).we use these CSS sheet.

We can use CSS sheet in two methods like INTERNAL and EXTERNAL style sheet.

1. INTERNAL STYLE SHEET:
In this we simply placing the CSS code in within the tags of each (X) HTML file.
The format is like:
