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The “profile” attribute on the “head” element is obsolete.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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Attribute “about” not allowed on element “article” at this point.
Attribute “content” not allowed on element “span” at this point.
Duplicate ID “prhc_newsletter_simple”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The first occurrence of ID “prhc_newsletter_simple” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
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).
