Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
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.
Stray end tag “meta”.
Bad value “Pragma” for attribute “http-equiv” on element “meta”.
Bad value “expires” for attribute “http-equiv” on element “meta”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “head” is missing a required instance of child element “title”.
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”.
Element “title” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
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.
Attribute “alt” not allowed on element “a” at this point.
No space between attributes.
Bogus comment.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “prevportada”.
Bad value for attribute “href” on element “a”: Illegal character in query: space is not allowed.
Element “h4” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “true” for attribute “allowfullscreen” on element “iframe”.
Attribute “webkitallowfullscreen” not allowed on element “iframe” at this point.
Attribute “mozallowfullscreen” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “img” is missing required attribute “src”.
Bad value “d1-active” for attribute “rel” on element “a”: The string “d1-active” is not a registered keyword.
Bad value “d2-active” for attribute “rel” on element “a”: The string “d2-active” is not a registered keyword.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Start tag “a” seen but an element of the same type was already open.
End tag “div” seen, but there were open elements.
Unclosed element “a”.
Stray end tag “script”.
The element “button” must not appear as a descendant of the “a” element.
The element “iframe” must not appear as a descendant of the “a” element.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
End tag for “body” seen, but there were unclosed elements.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “prevportada” was here.
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).
The document is not mappable to XML 1.0 due to a trailing hyphen in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
