HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “l” instead.
The “tt” element is obsolete. Use CSS instead.
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 “strong”.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “banner” role is unnecessary for element “header”.
The “main” role is unnecessary for element “main”.
