HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy encoding “windows-1251” used. Documents must use UTF-8.
Bad value “text/html; charset=windows-1251” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
The “center” element is obsolete. Use CSS instead.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “font” element is obsolete. Use CSS instead.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in Russian. Consider adding “lang="ru"” (or variant) to the “html” start tag.
