Why Validate?

You could compare validating your HTML to having your English composition checked by a teacher for grammar, syntax, spelling and so on. Validation allows you to see how your document complies to the Web Standards published by the World Wide Web Consortium (W3C) for HTML and XML document types.

Because different browsers interpret and display certain aspects of the same page in slightly different ways, validating your markup is an important step towards ensuring uniformity across browsers and operating platforms.

Plus, you will want to stay on the right side of emerging laws that require Web sites to be accessible to all users, regardless of disability or the technology used.
