This document discusses the importance of W3C validation for websites. W3C validation checks HTML and CSS codes to improve user experience by fixing formatting errors, reducing file size and page load times. Validating codes also improves accessibility across multiple devices as browsing shifts to mobile. Validated websites are considered higher quality and better for search engine optimization as search engines can more easily index content structured correctly.

be a major reason why your website should
be W3C validated.
