HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Empty heading.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
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:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “h1” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
