HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “” for attribute “name” on element “button”: Must not be empty.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Bad value “https://www1.chester.ac.uk/course_search?f[]=search_api_aggregation_7:Chester&s=master+of+business+administration” for attribute “href” on element “a”: Illegal character in query: “[” is not allowed.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “div” at this point.
Element “a” is missing one or more of the following attributes: “aria-checked”, “role”.
Bad value “tel:+441244 511000” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Warnings:
Attribute “"” is not serializable as XML 1.0.
The “contentinfo” role is unnecessary for element “footer”.
This document appears to be written in English but the “html” start tag has an empty “lang” attribute. Consider using “lang="en"” (or variant) instead.
