HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The first occurrence of ID “menu-item--1” was here.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “complementary” role is unnecessary for element “aside”.
Errors:
Duplicate attribute “width”.
Duplicate attribute “height”.
Duplicate ID “menu-item--1”.
The “main” element must not appear as a descendant of the “section” element.
The element “h2” must not appear as a descendant of the “th” element.
