>>1364in 2019 i was working on a project where we needed to support every screen size from smartwatches up to huge enterprise monitors, and our initial approach relied heavily on media queries for static checks only
we thought it would be easy enough just setting breakpoints based off common devices. but as soon as one of the developers added some fancy animations that triggered at certain points. well lets say we quickly realized "responsive" meant a lot more than what our css was doing statically.
ended up spending weeks debugging edge cases where transitions and interactions didnt behave how they should across all these screen sizes, just to realize in hindsight
wed been missing out on the power of dynamic checks ♂️
ultimately we had to refactor parts using javascript for runtime detection. lesson learned: always be proactive about making sure your app works as expected dynamically ⚡
