HTML markup errors and warnings
(Rescan now...)
Warnings:
Using “windows-1252” instead of the declared encoding “iso-8859-1”.
The “type” attribute is unnecessary for JavaScript resources.
This document appears to be written in Spanish. Consider adding “lang="es"” (or variant) to the “html” start tag.
Errors:
Legacy encoding “windows-1252” used. Documents must use UTF-8.
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
The “center” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
A “script” element with the “language="JavaScript"” attribute set must not have a “type” attribute whose value is not “text/javascript”.
Unmappable byte sequence: “90”.
Forbidden code point U+0002.
