HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “audience” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Attribute “target” not allowed on element “div” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “navigation” role is unnecessary for element “nav”.
Text run is not in Unicode Normalization Form C.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “form” role is unnecessary for element “form”.
