Attribute “aria-labelled-by” not allowed on element “ul” at this point.
Duplicate ID “menu-main”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

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).
