HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
Bad value “120px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “169px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “sidebar”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The value of attribute “alt” on element “img” from namespace “http://www.w3.org/1999/xhtml” is not in Unicode Normalization Form C.
The first occurrence of ID “sidebar” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in French. Consider adding “lang="fr"” (or variant) to the “html” start tag.
