(Rescan now...)
Errors:
Bad value “submin” for attribute “type” on element “button”.
Duplicate ID “title-search”.
Bad value “tel:8 800 333 00 23” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Element “h1” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “style”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The first occurrence of ID “title-search” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in Russian but the “html” start tag has “lang="en"”. Consider using “lang="ru"” (or variant) instead.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
