HTML Validator

 
The errors and warnings are generated by Tidy. This program is originally developed by the Web Consortium W3C.

Tidy is a helpful program that tries to help people to correct their HTML errors. It finds HTML errors and classifies them in 2 categories:
- warnings: HTML errors that Tidy can fix automatically
- errors: critical HTML errors that Tidy cannot fix or understand.

If you have only Warnings, press on the "Clean up" button and Tidy will do his best to propose you a cleaned version of your page.
