A static site still designates a site with no server-side processing, just serving of (static) content. As for it being plain HTML, no, it can be full of JS, videos, whatever, it&#x27;s still static.<p>I do remember a time when the expression &quot;dynamic HTML&quot; was popular to designate HTML+JS. Therefore, &quot;static&quot; may have been used in contrast to &quot;dynamic&quot; to designate plain HTML pages indeed. This is not the case now.
