HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in Spanish but the “html” start tag has “lang="en"”. Consider using “lang="es"” (or variant) instead.
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
No “p” element in scope but a “p” end tag seen.
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The “frameborder” attribute on the “iframe” element is obsolete.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.
Bad value “35px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “alt” not allowed on element “a” at this point.
