HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “navigation” not allowed as child of element “nav” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “logo” not allowed as child of element “header” in this context. (Suppressing further errors from this subtree.)
Element “cover” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray end tag “cover”.
Element “item” not allowed as child of element “main” 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 document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
