HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “https://www3.smartadserver.com/ac?jump=1&nwid=1832&siteid=133291&pgname=all&fmtid=40009&visit=m&tmstp=[timestamp]&out=nonrich” for attribute “href” on element “a”: Illegal character in query: “[” is not allowed.
Bad value “https://www3.smartadserver.com/ac?out=nonrich&nwid=1832&siteid=133291&pgname=all&fmtid=40009&visit=m&tmstp=[timestamp]” for attribute “src” on element “img”: Illegal character in query: “[” is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “last_article”.
No “p” element in scope but a “p” end tag seen.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “last_article” was here.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
