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.
Stray end tag “i”.
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
Text not allowed in element “ul” in this context.
The “center” element is obsolete. Use CSS instead.
Bad value “” for attribute “media” on element “link”: Media query ended prematurely.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “main” role is unnecessary for element “main”.
Empty heading.
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).
