HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “” for attribute “id” on element “ul”: 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.
Bad value “280 ” for attribute “height” on element “img”: Expected a digit but saw “ ” instead.
Stray end tag “strong”.
End tag “p” seen, but there were open elements.
Unclosed element “i”.
Element “p” not allowed as child of element “i” in this context. (Suppressing further errors from this subtree.)
End tag “i” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
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The “border” attribute is obsolete.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The “language” attribute on the “script” element is obsolete.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.
