End tag “nav” seen, but there were open elements.
Unclosed element “ul”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Duplicate attribute “title”.
No space between attributes.

End tag “div” seen, but there were open elements.
Stray end tag “ul”.
