HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “9c847c479331cda5f62fe46f-” for attribute “type” on element “script”: Subtype missing.
Stray start tag “a”.
Stray end tag “a”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “nslick” not allowed on element “li” at this point.
Attribute “toshow” not allowed on element “li” at this point.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “navigation” role is unnecessary for element “nav”.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
