HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “main_nav” was here.
The first occurrence of ID “middle” was here.
Errors:
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
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.
Duplicate ID “main_nav”.
Duplicate ID “middle”.
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.
