HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
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).
Attribute “” is not serializable as XML 1.0.
Errors:
Bad value “//www.googletagmanager.com/ns.html?id=GTM-KWC6BQ<http://www.googletagmanager.com/ns.html?id=GTM-KWC6BQ>” for attribute “src” on element “iframe”: Illegal character in query: “<” is not allowed.
The “font” element is obsolete. Use CSS instead.
End tag “br”.
Bad value “” for attribute “tabindex” on element “div”: The empty string is not a valid integer.
Bad value “http://” for attribute “href” on element “a”: Invalid host: empty host.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
A slash was not immediately followed by “>”.
Attribute “” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
