    What does W3 Validation and all that mean?

    How does a website become validated with W3 XHTML and CSS. What is it about that website that makes it validated, etc. Is it something about the way the code is programmed? Is it a certain kind of scripting language?

    The validator is a program that reads your markup and check for conformity to w3c specifications.

    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.

    Validating Web documents is an important step which can 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 document types include the HTML (through HTML 4.01) and XHTML (1.0 and 1.1) family, MathML, SMIL and SVG (1.0 and 1.1, including the mobile profiles). The Markup Validator can also validate Web documents written with an SGML or XML DTD, provided they use a proper document type declaration.
    if your markup is validated by the program, you can proudly add an image that says so

    If your code doesn't validate then it will not work properly on modern web browsers because the validation is done against the standards that the modern browsers follow. Older version 7 and earlier browsers don't follow the standards as closely and so let you get away with some things.

    And don't forget the CSS validator at http://jigsaw.w3.org/css-validator
    We are Linux, you will be assimilated, you will be liberated, you will be confused by our version numbers and installation procedures, resistance is futile...

    Trying to optimize a Web page/site for a particular browser is like trying to optimize Tokyo for Godzilla. It's just not going to work.
