Need advice on how to make a similar design

Hello everyone :) I am making a project right now, kind of like a coursework for my Web Development uni subject. I want to make something complex so that I could use it not only for uni, but also for my portfolio in the future. To give you some examples of what I’m talking about here is this website: https://www.eleken.co/saas-web-d... I know it was built using webflow, maybe someone here could help me with implementing something like this, or maybe telling me where to start. I’m completely new to webflow :( Thanks!
