Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).

Bad value “text/span; charset=utf-8” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.

End tag “div” seen, but there were open elements.

Unclosed element “a”.

Start tag “a” seen but an element of the same type was already open.

End tag “a” violates nesting rules.

Cannot recover after last error. Any further errors will be ignored.

Warnings

Attribute “xmlns” is not serializable as XML 1.0.

The “type” attribute is unnecessary for JavaScript resources.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
