HTML and CSS

I want to know how to professional Frontend developers manage the responsiveness to match different devises. Ok i am saying this because i did the card for desktop and Mobile and both are ok and for sure if anyone has comment on the code to have better or easier one that would be great. and i did for desktop and mobile only because this is the task. but i was planning to make it for tablet and smaller size of laptops and etc... So how to developers manage this, do they do media query for each range of sized expected, or do they depend on bootstrap or any other framework or what ?
