J'ai voulu analysé une de mes pages sur W3C mais j'obtiens une erreur :evil: .
Error Line 7 column 6: end tag for "html" which is not finished.
</html>
Most likely, You nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p>
Another possibility is that you used an element which requires a child element that you did not include. Hence the parent element is "not finished", not complete. For instance, <head> generally requires a <title>, lists (ul, ol, dl) require list items (li, or dt, dd), and so on.
