bonjour,
je viens de tester mes sites sur validator.w3.org
quelqu'un peut-il m'expliquer dans un langage simple :? de quoi il s'agit et comment palier ce manque ? est-ce important ? merci beaucoup !
No DOCTYPE found!
Attempting validation with HTML 4.01 Transitional. The DOCTYPE Declaration was not recognized or is missing. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax. Validation has been performed using a default "fallback" Document Type Definition that closely resembles "HTML 4.01 Transitional", but the document will not be Valid until you have corrected this problem with the DOCTYPE Declaration.
Error Line 1 column 0: no document type declaration; implying "<!DOCTYPE HTML SYSTEM>".
<html>
The checked page did not contain a document type ("DOCTYPE") declaration. The Validator has tried to validate with a fallback DTD, but this is quite likely to be incorrect and will generate a large number of incorrect error messages. It is highly recommended that you insert the proper DOCTYPE declaration in your document -- instructions for doing this are given above -- and it is necessary to have this declaration before the page can be declared to be valid.
