HTML markup errors and warnings
(Rescan now...)
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
The element “header” must not appear as a descendant of the “header” element.
Bad value “modal” for attribute “role” on element “a”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value “dropdown” for attribute “role” on element “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 “modal” for attribute “role” on element “button”.
Element “img” is missing required attribute “src”.
Bad value “https://borrow.bklynlibrary.org/iii/encore/search/C__S(*) f:(h | v | g) y:[2017-2017]__Orightresult__U” for attribute “href” on element “a”: Illegal character in path segment: space is not allowed.
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.
The “navigation” role is unnecessary for element “nav”.
