I’m currently learning Frontend and I have a question. I am working on a team project I have a question due to a disagreement The only FE in this team so I have nowhere else to ask.

Team Leader keeps suggesting on managing Mobile and Web pages/components seperately instead of using responsive web because he think it’s better to manage later in the project. We also have a APP in development and it’s a big project.

However, I disagree and think using responsive web (currently using tailwind CSS) is much more efficient to manage. Also creating seperate files will just make state management much more difficult as well.

Is it a common thing to manage mobile and web files seperately or is it okay just using responsive web?

Also what could be possible up/downsides of managing it only using responsive web?

I looked it up on the web, but it seems just using responsive web is okay?
