HTML markup errors and warnings
(Rescan now...)
Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Attribute “<” not allowed on element “ins” at this point.
Attribute “ins” not allowed on element “ins” at this point.
End tag “div” seen, but there were open elements.
Unclosed element “ins”.
Stray end tag “div”.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Attribute “<” is not serializable as XML 1.0.
Text run is not in Unicode Normalization Form C.
This document appears to be written in German. Consider adding “lang="de"” (or variant) to the “html” start tag.
