HTML markup errors and warnings
(Rescan now...)
Errors:
A “charset” attribute on a “meta” element found after the first 1024 bytes.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
The element “a” must not appear as a descendant of the “button” element.
Bad value “769px 50vw, 100vw” for attribute “sizes” on element “img”: Bad media condition: Expected “(” or letter at start of a media query part but saw “7” instead at “769px 50vw,”.
Attribute “href” not allowed on element “span” at this point.
Stray end tag “div”.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “main”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
