Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Attribute “-” is not serializable as XML 1.0.
Attribute “vallee'” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Attribute “rel” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “http-equiv”, “itemprop”, “name”, “property”.
No space between attributes.
Bad value “50px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “href”.
No “li” element in scope but a “li” end tag seen.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
Duplicate attribute “alt”.
No “p” element in scope but a “p” end tag seen.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Attribute “alt” not allowed on element “a” at this point.
Element “option” without attribute “label” must not be empty.
Quote “'” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “europe” not allowed on element “option” at this point.
Attribute “-” not allowed on element “option” at this point.
Attribute “marne” not allowed on element “option” at this point.
Attribute “la” not allowed on element “option” at this point.
Attribute “vallee'” not allowed on element “option” at this point.
Bad value “” for attribute “name” on element “button”: Must not be empty.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “0/” for attribute “border” on element “img”: Only “0” is a permitted zero literal.
