HTML markup errors and warnings
(Rescan now...)
Errors:
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “http://certyfikatpolski.pl/wp-content/themes/certyfikatpolski/images/favicon_ceg.png"/” for attribute “href” on element “link”: Illegal character in path segment: “"” is not allowed.
Element “h2” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
