HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Stray start tag “html”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value for attribute “href” on element “a”: Illegal character in query: “[” is not allowed.
No space between attributes.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Bad value “” for attribute “name” on element “select”: Must not be empty.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “wp-video-lightbox” for attribute “rel” on element “a”: The string “wp-video-lightbox” is not a registered keyword.
End tag “form” seen, but there were open elements.
Unclosed element “div”.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “banner” role is unnecessary for element “header”.
