HTML markup errors and warnings
(Rescan now...)
Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Element “h2” 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 “https://www.columbuslibrary.org/sites/default/files/uploads/docs/CML-Strat Plan 2017.pdf” for attribute “href” on element “a”: Illegal character in path segment: space is not allowed.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
