Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “cache-control” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “topbar”.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Duplicate ID “compareContainerAjax”.
Bad value “_blanc” for attribute “target” on element “a”: Reserved keyword “blanc” used.
Attribute “alt” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.
Duplicate ID “”.
Element “h1” not allowed as child of element “strong” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “p” element is obsolete. Use CSS instead.
The “align” attribute on the “h3” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “div”.
Duplicate ID “newsletter_input”.
Duplicate ID “newsletter”.
Element “li” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Stray end tag “span”.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
End tag “p” implied, but there were open elements.
Unclosed element “a”.
No “a” element in scope but a “a” end tag seen.
