HTML markup errors and warnings
(Rescan now...)
Errors:
Attribute “href” not allowed on element “div” at this point.
The element “header” must not appear as a descendant of the “header” element.
Duplicate ID “qc_cta”.
Bad value “” for attribute “id” on element “section”: An ID must not be the empty string.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “ISO-8859-1” for attribute “charset” on element “script”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The first occurrence of ID “qc_cta” was here.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
