HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Garbage after “</”.
End tag “div” seen, but there were open elements.
Unclosed element “span”.
Bad value “true” for attribute “checked” on element “input”.
Duplicate ID “LJU”.
Duplicate ID “BTS”.
Element “option” without attribute “label” must not be empty.
Bad character “1” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Element “div” not allowed as child of element “dl” in this context. (Suppressing further errors from this subtree.)
No “dd” element in scope but a “dd” end tag seen.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The first occurrence of ID “LJU” was here.
The first occurrence of ID “BTS” was here.
This document appears to be written in German. Consider adding “lang="de"” (or variant) to the “html” start tag.
