Errors:
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.
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Premature end of comment. Use “-->” to end a comment properly.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “” for attribute “for” on element “label”: An ID must not be the empty string.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “autocapitalize” not allowed on element “input” at this point.
Attribute “autocorrect” not allowed on element “input” at this point.
Element “header” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “main” role is unnecessary for element “main”.
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.
