HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Bad character “=” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Element “div” not allowed as child of element “em” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Attribute “<” not allowed on element “img” at this point.
Attribute “a” not allowed on element “img” at this point.
End tag “td” seen, but there were open elements.
Unclosed element “a”.
Warnings:
Attribute “<” is not serializable as XML 1.0.
This document appears to be written in English but the “html” start tag has “lang="pl"”. Consider using “lang="en"” (or variant) instead.
