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.
Attribute “xtraffic-exclude” not allowed on element “script” at this point.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
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).
Document uses the Unicode Private Use Area(s), which should not be used in publicly exchanged documents. (Charmod C073)
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
