HTML markup errors and warnings
(Rescan now...)
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Errors:
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
The “font” element is obsolete. Use CSS instead.
Element “p” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
The “aria-labelledby” attribute must point to an element in the same document.
