HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Stray end tag “option”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “width” not allowed on element “tr” at this point.
The “width” attribute on the “td” element is obsolete. Use CSS instead.
Warnings:
The “banner” role is unnecessary for element “header”.
Empty heading.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “contentinfo” role is unnecessary for element “footer”.
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).
