HTML markup errors and warnings

(Rescan now...)

Errors:

Legacy encoding “windows-1250” used. Documents must use UTF-8.

Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)

Legacy doctype. Expected “<!DOCTYPE html>”.

Attribute “xmlns:og” not allowed here.

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 “text/html; charset=windows-1250” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.

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

Warnings:

Attribute with the local name “xmlns:og” is not serializable as XML 1.0.

The “type” attribute for the “style” element is not needed and should be omitted.

The “type” attribute is unnecessary for JavaScript resources.

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