Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Stray doctype.
Stray start tag “html”.
Start tag “head” seen but an element of the same type was already open.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “iso-8859-1” for attribute “charset” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Any “input” descendant of a “label” element with a “for” attribute must have an ID value that matches that “for” attribute.
Malformed byte sequence: “e1”.
Element “img” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “li” seen, but there were open elements.
Unclosed element “nav”.
Stray end tag “nav”.
No “p” element in scope but a “p” end tag seen.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
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).
