Web Page Validation & Validators

The W3C is the World Wide Web Consortium and provides guidelines based on best practice, regarding how websites and web pages should be structured and created for long-term durability. The W3C validation is a standard for specified machine language, checking web documents, spelling, grammar, syntax, and proofreading code.

A validator is a software program that can check your web pages against the web standards. When using a validator to check HTML, XHTML or CSS documents, the validator returns a list of errors found, according to your chosen standard. Make sure you make it a habit to validate all your web pages before publishing.
