HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Element “area” is missing required attribute “alt”.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Attribute “about” not allowed on element “div” at this point.
Duplicate ID “main-content”.
Duplicate ID “blockTHolder”.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “main-content” was here.
The first occurrence of ID “blockTHolder” was here.
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).
