HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
Attribute “alt” not allowed on element “input” at this point.
Attribute “alt” not allowed on element “a” at this point.
Start tag “a” seen but an element of the same type was already open.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “div” seen, but there were open elements.
Unclosed element “a”.
End tag “form” seen, but there were open elements.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
