End tag “g” did not match the name of the current open element (“svg”).
Stray end tag “g”.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.

Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Warnings:
