HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “rus” for attribute “lang” on element “html”: The language subtag “rus” is not a valid ISO language part of a language tag.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “title” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
