Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.

Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.

The “font” element is obsolete.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.

End tag “font” violates nesting rules.

No “strong” element in scope but a “strong” end tag seen.

The “width” attribute on the “table” element is obsolete. Use CSS instead.

The “valign” attribute on the “td” element is obsolete. Use CSS instead.

Element “area” is missing required attribute “alt”.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

The first occurrence of ID “paticka-kopirovat-odkaz” was here.

This document appears to be written in Czech. Consider adding “lang="cs"” (or variant) to the “html” start tag.
