Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
This document appears to be written in Indonesian. Consider adding “lang="id"” (or variant) to the “html” start tag.
