What is W3C Validator?

The W3C Validator, identified by the user agent 'w3c-validator', is a bot operated by the World Wide Web Consortium (W3C). Its primary function is to crawl and analyze web pages to verify their compliance with established web standards, particularly focusing on the validity of HTML and XHTML markup. By submitting a URL to the W3C Markup Validation Service, users trigger this bot to fetch and examine the page's source code. The validator checks for syntax errors, deprecated elements, and other issues that may affect interoperability and accessibility. The results help web developers ensure their sites adhere to best practices, improving browser compatibility and user experience. The W3C Validator is widely recognized and trusted in the web development community as an essential tool for maintaining high-quality, standards-compliant websites.
