Description: Validation markup refers to the practice of using code that ensures a web page adheres to standards set by organizations like the World Wide Web Consortium (W3C). This process involves reviewing HTML, CSS, and other markup languages to detect errors and ensure best practices are followed. Validation not only improves compatibility across different browsers and devices but also optimizes web performance by reducing the likelihood of errors that can slow down page loading or cause display failures. By adhering to standards, developers can ensure their websites are accessible and functional for a wide audience, which is crucial in an increasingly diverse digital environment. Additionally, validation markup contributes to SEO optimization, as search engines favor well-structured, error-free pages. In summary, validation markup is an essential tool in creating efficient and accessible websites that enhance user experience and boost online visibility.
