Bad value “true” for attribute “async” on element “script”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Duplicate ID “hot_bottom”.

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.

The first occurrence of ID “hot_bottom” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
