HTML markup errors and warnings
(Rescan now...)
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
Duplicate ID “ctabuttons”.
Bad value “disclaimerInner panel” for attribute “id” on element “div”: An ID must not contain whitespace.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “ctabuttons” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
