Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
“label” element with multiple labelable descendants.
This document appears to be written in German. Consider adding “lang="de"” (or variant) to the “html” start tag.
Errors:
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
Attribute “required” not allowed on element “input” at this point.
Attribute “required” is only allowed when the input type is “checkbox”, “date”, “datetime-local”, “email”, “file”, “month”, “number”, “password”, “radio”, “search”, “tel”, “text”, “time”, “url”, or “week”.
Element “option” without attribute “label” must not be empty.
The “label” element may contain at most one “button”, “input”, “meter”, “output”, “progress”, “select”, or “textarea” descendant.
Duplicate attribute “id”.
The “align” attribute on the “img” element is obsolete.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.
