HTML markup errors and warnings
(Rescan now...)
Errors:
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Warnings:
This document appears to be written in Russian. Consider adding “lang="ru"” (or variant) to the “html” start tag.
