HTML markup errors and warnings
(Rescan now...)
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”.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Attribute “value” not allowed on element “a” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “li” seen, but there were open elements.
Unclosed element “form”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
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.
Stray end tag “div”.
Stray end tag “main”.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
