HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad value “schema.AGLSTERMS” for attribute “rel” on element “link”: The string “schema.AGLSTERMS” is not a registered keyword.
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 “name” on element “button”: Must not be empty.
Element “div” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “navigation” role is unnecessary for element “nav”.
The “complementary” role is unnecessary for element “aside”.
