HTML Validation
HTML Validation is the process of checking HTML code against established standards, such as those set by the World Wide Web Consortium (W3C), to ensure it is syntactically correct and follows best practices. It involves using validators to detect errors like missing tags, improper nesting, or deprecated attributes, which helps improve code quality, accessibility, and cross-browser compatibility. This process is essential for creating robust, standards-compliant web pages that function reliably across different devices and platforms.
Developers should use HTML validation during web development to catch syntax errors early, reduce debugging time, and ensure their code adheres to web standards, which enhances accessibility for users with disabilities and improves SEO rankings. It is particularly crucial in professional environments where code maintainability and compliance with regulations like WCAG (Web Content Accessibility Guidelines) are required, such as in e-commerce sites, government portals, or educational platforms.
