A dynamic website is generated by the server in response to client queries. Static websites—pre-existing flat html files served as-is to viewers—came first, then PHP and CGI made dynamic websites possible & popular. SSR is the very definition of a dynamic website. Client-side scripting came after dynamic websites, but it is not technically, in and of itself, "dynamic."

The trouble is defining what "the content" means. Are you saying "no JS" — if so, just say so! Otherwise, how are you distinguishing between "content" and ... "other stuff"?
