(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “p” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Bad value “” for attribute “cols” on element “textarea”: The empty string is not a valid positive integer.
Bad value “” for attribute “name” on element “input”: Must not be empty.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Element name “o:p” cannot be represented as XML 1.0.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in Russian. Consider adding “lang="ru"” (or variant) to the “html” start tag.
