HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Bad value “Top” for attribute “rel” on element “link”: The string “Top” is not a registered keyword.
Bad value “/Szukaj” for attribute “rel” on element “a”: The string “/Szukaj” is not a registered keyword.
Bad value “/Ustawa-2.0-w-PW” for attribute “rel” on element “a”: The string “/Ustawa-2.0-w-PW” is not a registered keyword.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Bad value “prettyphoto” for attribute “rel” on element “a”: The string “prettyphoto” is not a registered keyword.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Warnings:
The “type” attribute for the “style” element is not needed and should be omitted.
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
