Warnings:

The “button” role is unnecessary for element “button”.
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The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
