(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
The string following “&” was interpreted as a character reference. (“&” probably should have been escaped as “&”.)
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 “bogus” for attribute “media” on element “link”: Expected a CSS media type but the query ended.
The “for” attribute on the “script” element is obsolete. Use DOM Events mechanisms to register event listeners.
The “event” attribute on the “script” element is obsolete. Use DOM Events mechanisms to register event listeners.
Attribute “sid” not allowed on element “a” at this point.
Attribute “tid” not allowed on element “a” at this point.
Duplicate ID “btn_menu_genre”.
Attribute “sid” not allowed on element “input” at this point.
Attribute “tid” not allowed on element “input” at this point.
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Bad value “true” for attribute “async” on element “script”.
Warnings:
The first occurrence of ID “btn_menu_genre” was here.
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
