Errors:
Legacy 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).
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Attribute “alt” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Duplicate attribute “Любимые”.
Duplicate attribute “питомцы"”.
Duplicate attribute “"”.
Stray end tag “a”.
Duplicate ID “media-list”.
Element “up” not allowed as child of element “i” in this context. (Suppressing further errors from this subtree.)
Element “down” not allowed as child of element “i” in this context. (Suppressing further errors from this subtree.)
End tag “br”.
Duplicate attribute “class”.
Duplicate ID “topic_list_image”.
The string following “&” was interpreted as a character reference. (“&” probably should have been escaped as “&”.)
Attribute “;” not allowed on element “a” at this point.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “питомцы"” is not serializable as XML 1.0.
Attribute “"” is not serializable as XML 1.0.
The first occurrence of ID “media-list” was here.
The first occurrence of ID “topic_list_image” was here.
Attribute “;” is not serializable as XML 1.0.
This document appears to be written in Russian. Consider adding “lang="ru"” (or variant) to the “html” start tag.
