I apologize if this is such a bad question but I have zero clue about web or UI design. I'm a graphic designer but I was tasked to just design a website using Photoshop cause that's what I'm familiar with.
Now I'm tasked to convert that web design I did to a mobile version. Which I totally get since the layout would entirely change in a phone. I'm trying to learn figma and watching videos about converting your web design to mobile. And I heard about "responsive" and making your design adaptive. So what they would do is freely size the artboard and the layout just follows. Which I thought was cool, but what is the point of that?
Don't I only need one design for desktop, and another layout for a mobile? Aren't the developers in charge of that? Since my design is only for reference anyway and the output I'll give them is just a static image?
