HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “pl_PL” for attribute “lang” on element “html”: The language subtag “pl_pl” is not a valid language subtag.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
End tag “li” seen, but there were open elements.
Unclosed element “div”.
End tag “br”.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
