Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “button_sells_more” was here.
This document appears to be written in Spanish. Consider adding “lang="es"” (or variant) to the “html” start tag.
Errors:
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.
Bad value “” for attribute “name” on element “input”: Must not be empty.
Bad value “” for attribute “id” on element “a”: An ID must not be the empty string.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
