FAQ
Correct HTML ensures that pages display correctly, improves SEO and accessibility for users with special needs.
It is recommended that you validate every time you make a major change to your page structure or before launching new features.
Browsers often ignore minor bugs, but they can break SEO, accessibility, or cause problems with updates. Validation helps prevent hidden bugs.
Use the tooltips in the report: click on the error to see a description and examples of fixes. For example, add missing attributes or fix tag nesting.
The validator checks for standards compliance, but not functionality. Check JavaScript code, styles and server-side scripts separately. Use developer tools in the browser to troubleshoot.
