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).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
