The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.
Mismatch between Public and System identifiers in the DOCTYPE declaration
This document uses an inconsistent DOCTYPE declaration.
The Public Identifier
-//W3C//DTD XHTML 1.0 Strict//EN declares the
XHTML 1.0 Strict document type, but the associated System Identifier
http://www.w3.org/TR/xhtml1/DTD/xhtml10strict.dtd does not match this document type.
The recommended System Identifier
for XHTML 1.0 Strict is http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd.
The safest way to use a correct DOCTYPE declaration is to copy and paste one from the recommended list and avoid editing that part of your markup by hand.

"async" is not a member of a group specified for any attribute
…ht:90px;margin:0 auto;"><script async src="https://ndroip.com/na/waWQiOjEwNzIx……Swid2lkIjoxNjAwNzQsInNyYyI6Mn0=eyJ.js"></script></div></div><!--WZ-REKLAMA-1.0…The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.
Typical values for type are
type="text/css" for <style>
and type="text/javascript" for <script>.
