HTML markup errors and warnings
(Rescan now...)
Errors:
End tag “li” seen, but there were open elements.
Unclosed element “div”.
Stray end tag “div”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “button” for attribute “type” on element “a”: Subtype missing.
Duplicate ID “logos”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
End tag “section” seen, but there were open elements.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
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).
The first occurrence of ID “logos” was here.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
