Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
