HTML markup errors and warnings
(Rescan now...)
Errors:
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
End tag “article” seen, but there were open elements.
Unclosed element “div”.
Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “navigation” for attribute “role” on element “ul”.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “main” role is unnecessary for element “main”.
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).
