HTML markup errors and warnings
(Rescan now...)
Errors:
Attribute “itemprop” not allowed on element “meta” at this point.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “alert” for attribute “role” on element “aside”.
Duplicate attribute “data-type”.
Attribute “data” not allowed on element “input” at this point.
Duplicate attribute “class”.
Bad value “” for attribute “src” on element “audio”: Must be non-empty.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The “for” attribute of the “label” element must refer to a non-hidden form control.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Empty heading.
