I validated a website and got this answer, the problem is I don’t what I have to do to get it correct so I would appreciate any information I can get.
Congratulations
The uploaded document “index.htm” was tentatively checked as HTML 4.01 Transitional. This means that with the use of some fallback or override mechanism, we successfully performed a formal validation using an SGML or XML Parser. In other words, the document would validate as HTML 4.01 Transitional if you changed the markup to match the changes we have performed automatically, but it will not be valid until you make these changes.
