HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “Cache-control” for attribute “http-equiv” on element “meta”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Character reference was not terminated by a semicolon.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “align” attribute on the “h2” element is obsolete. Use CSS instead.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “main” role is unnecessary for element “main”.
The “contentinfo” role is unnecessary for element “footer”.
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).
