About this tool

Checks submitted HTML code against established web standards to ensure structural integrity and compliance with W3C specifications. Users paste their markup into a dedicated field, and the tool analyzes the syntax for common errors like unclosed tags or improperly nested elements. It processes the input to identify areas where the code deviates from best practices, providing detailed reports on both technical malformation and potential accessibility gaps within the structure. Developers and web designers frequently utilize this utility during the development lifecycle of a website. Incorporating the validator helps professionals catch critical bugs early, improving the reliability and robustness of their sites before they go live.
