HTML markup errors and warnings
(Rescan now...)
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
The “main” role is unnecessary for element “main”.
The first occurrence of ID “Layer_1” was here.
Attribute with the local name “xmlns:sketch” is not serializable as XML 1.0.
The “textbox” role is unnecessary for an “input” element that has no “list” attribute and whose type is “text”.
Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
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 “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Duplicate ID “Layer_1”.
Attribute “xmlns:sketch” not allowed here.
No “p” element in scope but a “p” end tag seen.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
