How to Provide Feedback
For the W3C Markup Validator

If your page doesn't validate, and you don't know why, or you have a question about HTML or validation:

First, check our Help and FAQ document, as well as the Web authoring FAQ to see if your question has been answered there.

The two most common problems are:

  • Validating pages with &'s in URLs: see Ampersands (&'s) in URLs
  • Validating pages with JavaScript: see Writing HTML in a SCRIPT Element

If your problem isn't covered by one of the resources above, you can send it to one of the following forums:

Each of these forums have plenty of experienced HTML authors who are willing to share their expertise. If you are commenting on a specific page, be sure to provide a URL when you ask your question!

If you are interested in helping to improve this service, by writing code or just providing ideas:

Please join and contribute to the www-validator mailing list.

If you just have a small patch or idea and don't want to join the list, feel free to .

If you want to report a bug or log a feature request:

The W3C maintains a public bug tracking database known as Bugzilla where developers and other technical users can log bug reports and feature suggestions directly. If you are not familiar with issue tracking systems in general or the Bugzilla bug tracker, send your feedback to the mailing list and someone on the W3C Validator Team will take care of logging your issue as appropriate.
