HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “validationgroup” not allowed on element “label” at this point.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “noscript” in this context. (Suppressing further errors from this subtree.)
A table row was 8 columns wide and exceeded the column count established using column markup (3).
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in Russian. Consider adding “lang="ru"” (or variant) to the “html” start tag.
