You need to learn. To learn you need to break down the general “how” into specific questions and find answers to them. To find answers you need to google.
Responsiveness really sucks on Figma, especially autolayouts… by default a canvas should be responsive and everything inside of it should adapt by default. I saw that the new changes in AutoLayout are going to be smarter but I am not sure if it is going to work like xd used to with their canvas. Most designs need some sort of responsiveness/adaptability… it will be great to be able to turn any design to responsive instead of going layer by layer switching every layer to “fill” —really annoying!!!
