Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Attribute “name” not allowed on element “meta” at this point.
Bad value “width=device-width, initial-scale=1, maximum-scale=1;text/html; charset=iso-8859-1” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
The “center” element is obsolete. Use CSS instead.
Attribute “\” not allowed on element “br” at this point.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “\” is not serializable as XML 1.0.
This document appears to be written in Spanish but the “html” start tag has “lang="en"”. Consider using “lang="es"” (or variant) instead.
