HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
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The “align” attribute on the “h3” element is obsolete. Use CSS instead.
The “align” attribute on the “h1” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Empty heading.
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).
