Can adaptive layout on flexbox be considered a full-fledged adaptive layout?

Question

css

Hello.
Got a question. There are 2 options.
1. The first option. Imagine that there is a layout for the desktop version and I was told to make an adaptive layout. If I make it using flexbox, where when the screen is squeezed, everything will be successfully rebuilt both on the tablet and on mobile devices, will this be considered a full-fledged layout? And text fonts can already be corrected in media queries.
Or a full-fledged adaptive layout only when everything is completely rebuilt on media queries?
2. And the second option. If there is a layout of a mobile, tablet, desktop view, is it only through media queries to make adaptability?
I'm a little confused just what is considered a full-fledged adaptive layout and what is not.

Answer 1

Responsive layout is a layout that adapts to a range of screens while maintaining a comfortable interaction with the interface. Do you do it on Flexbox or Float, it doesn't matter. With or without media queries, it doesn't matter.
