This form allows you to submit an HTML document for validation. The responses are somewhat cryptic. We hope to rectify this in the future.
The validation service is now able to check the various levels of HTML conformance:
Strict Level 0 Level 1 Level 2 Level 3 Mozilla
Also, in response to feedback from some users, much of the obscure information is excluded from the reponse unless you elect to see it:
Show Input Show Parser Output Show Formatted Output
Enter the URLs of the documents you wish to check:
If you just have a quick question, rather than constructing a document and giving the address, you can enter your test data here: (be sure to erase any URLs above first!)
Enter bits of HTML you have a question about: <!-- select doctype above... --> <HEAD> <TITLE><!-- your title here --></TITLE> </HEAD> <BODY> <!-- your HTML test data --> </BODY>
