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.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Bad value “follow” for attribute “rel” on element “a”: The string “follow” is not a registered keyword.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Element “br...” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
End tag “p” implied, but there were open elements.
Unclosed element “br...”.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “<” is not serializable as XML 1.0.
This document appears to be written in German. Consider adding “lang="de"” (or variant) to the “html” start tag.
