Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “contentinfo” role is unnecessary for element “footer”.
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).
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “img” is missing required attribute “src”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
