This question is more for anything than this project itself but it's because of it that I wanna ask. Do you guys make your projects responsive for absolutely all media screens? For example, this project "breaks" in a nokia with 240x320 screen size, but then I thought, "why I gonna make this works on this little specific screen size... I'm wrong to think this or not?

I'm unsure of the way I did to do spacing between the words and icons from the right part. I'm sure there's a better way to do this but idk how. Like, the actual space is proportional from the 3 parts because I'm using "space-between" from "justify-content", idk how to do a smaller space between the icon and text, and a bigger space between the text and grade. As a matter of fact, I'm actually know some ways to do, but I'm sure there are better ways, so I'm open to listen from community :V!
