HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Obsolete doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The element “button” must not appear as a descendant of the “a” element.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “scr” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray end tag “script”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “scr”.
Warnings:
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
Consider avoiding viewport values that prevent users from resizing documents.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
