Errors:
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
Bad value “dofollow” for attribute “rel” on element “a”: The string “dofollow” is not a registered keyword.
Stray end tag “div”.
Bad value “true” for attribute “async” on element “script”.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:

This document appears to be written in Spanish. Consider adding “lang="es"” (or variant) to the “html” start tag.
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).
