What are the “components” that we measure using the TTFB (First Byte) value?

I assume that TTFB metric, relate to the HTML page that the Web server sends to his Web client in the “first-time phase” when the Web client connects the Web server.

But, what about the rest of the communication channel between the Web client and the Web server?

In case that the HTML page includes links to additional Resource\Assets such as Java Scripts and CSS file, the Web client will need to create an additional request asking for this “Resource\Assets”.

Given that the Web browser asks from the Web server to get a specific resource such as CSS file, do we still use the TTFB metric for measuring the amount of time until the Web browser gets the First Byte (of the CSS file in our example)?

Or, the use of the term “TTFB” is related only to the initialization phase in which the Web browser is “waiting” for the HTML page that the Web server needs to send?
