HTML markup errors and warnings
(Rescan now...)
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “navigation” role is unnecessary for element “nav”.
The “textbox” role is unnecessary for an “input” element that has no “list” attribute and whose type is “text”.
This document appears to be written in Greek but the “html” start tag has an empty “lang” attribute. Consider using “lang="el"” (or variant) instead.
Errors:
Attribute “alt” not allowed on element “input” at this point.
No “p” element in scope but a “p” end tag seen.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “summary” attribute on the “table” element is obsolete.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.
Attribute “day” not allowed on element “a” at this point.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “li” seen, but there were open elements.
Unclosed element “div”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
