HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “en_GB” for attribute “lang” on element “html”: The language subtag “en_gb” is not a valid language subtag.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Bad value “menubar” for attribute “role” on element “nav”.
The element “header” must not appear as a descendant of the “header” element.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “div” at this point.
CSS: “text-align”: Too many values or values are not recognized.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Attribute “"” is not serializable as XML 1.0.
