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.
Element “li” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Attribute “xmlns:svg” not allowed here.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “main” role is unnecessary for element “main”.
Attribute with the local name “xmlns:svg” is not serializable as XML 1.0.
Unsupported SVG version specified. This validator only supports SVG 1.1. The recommended way to suppress this warning is to remove the “version” attribute altogether.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “contentinfo” role is unnecessary for element “footer”.
