Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “charset” attribute on the “link” element is obsolete. Use an HTTP Content-Type header on the linked resource instead.
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 “javascript” for attribute “type” on element “script”: Subtype missing.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
