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The “profile” attribute on the “head” element is obsolete.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 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.
Attribute “defer” not allowed on element “link” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “Book your service online” for attribute “type” on element “a”: Expected a token character or “/” but saw “ ” instead.
Attribute “alt” not allowed on element “a” at this point.
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
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.
