HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Attribute “n” not allowed on element “meta” at this point.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “img” is missing required attribute “src”.
Element “hr” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “fb-root”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “fb-root” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
