HTML markup errors and warnings
(Rescan now...)
Errors:
Garbage after “</”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.

Attribute “increase” not allowed on element “button” at this point.
Attribute “font” not allowed on element “button” at this point.
Attribute “size"” not allowed on element “button” at this point.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
