Approach this problem like a freecodecamp dynamic webpage project - write problem statements, goals and user stories - break up the design into page structure and layout, code and styling - is it pure clientside or is it client-server with database - break down the problems into smaller and smaller chunks - solve a small problem and test
feeling lost is a sure sign you are looking at a problem description that is too vague or general - you need to pick one or more parts of problem to refine and flesh out till you reach descriptions you can completely understand
