HTML markup errors and warnings

(Rescan now...)

Errors:

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

Bad value “ http:=” for attribute “href” on element “a”: Expected a slash ("/").

Bad value “100px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.

No “p” element in scope but a “p” end tag seen.

The “itemprop” attribute was specified, but the element is not a property of any item.

Warnings:

The “border” attribute is obsolete.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

The “navigation” role is unnecessary for element “nav”.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

This document appears to be written in Russian but the “html” start tag has “lang="en"”. Consider using “lang="ru"” (or variant) instead.
