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”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “fallback” not allowed on element “img” at this point.
No “li” element in scope but a “li” end tag seen.
Attribute “alt” not allowed on element “input” at this point.
Element “figcaption” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “” for attribute “id” on element “ul”: An ID must not be the empty string.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “type” not allowed on element “textarea” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Empty heading.
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 document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
