Errors:
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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “schema.DC” for attribute “rel” on element “link”: The string “schema.DC” is not a registered keyword.
The “scheme” attribute on the “meta” element is obsolete. Use only one scheme per field, or make the scheme declaration part of the value.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
Bad value “600px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “phone” for attribute “type” on element “input”.
Bad value “name” for attribute “type” on element “input”.
End tag “br”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Duplicate ID “frm_dialog”.
Attribute “ref” not allowed on element “a” at this point.
Bad value “false” for attribute “autocomplete” on element “input”: The string “false” is not a valid autofill field name.
Duplicate ID “details_channel”.
Bad value “true” for attribute “checked” on element “input”.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “frm_dialog” was here.
The “form” role is unnecessary for element “form”.
The first occurrence of ID “details_channel” was here.
