Element “div” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Attribute “type” not allowed on element “article” at this point.
Attribute “timestamp” not allowed on element “article” at this point.
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “td” seen, but there were open elements.
Unclosed element “a”.
Attribute “offset” not allowed on element “td” at this point.
Attribute “starttime” not allowed on element “td” at this point.
Attribute “endtime” not allowed on element “td” at this point.
Table column 4 established by element “td” has no cells beginning in it.
Warnings:

A table row was 4 columns wide and exceeded the column count established by the first row (3).
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
