Frequently Asked Questions

Why validate HTML?

Validating HTML helps ensure that your pages render correctly across different browsers, improves SEO, and ensures accessibility for screen readers.

Is this as strict as W3C?

This tool uses the native browser parser to detect structural failures. For full standards compliance (DTD/XSD), the W3C service is recommended, but this is perfect for quick structural checks.
