HTML markup errors and warnings
(Rescan now...)
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate attribute “class”.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
The “align” attribute on the “td” element is obsolete. Use CSS instead.
Bad value “93px;” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
This document appears to be written in English but the “html” start tag has “lang="es"”. Consider using “lang="en"” (or variant) instead.
