HTML markup errors and warnings
(Rescan now...)
Errors:
Bogus doctype.
Quirky doctype. Expected “<!DOCTYPE html>”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root 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.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The element “button” must not appear as a descendant of the “a” element.
Element “p” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
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.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
