Not really. The only advice I can give is to start simple and work your way up. I think part of the problem OP is having is that they're trying to do too much at once. Menus are complex and probably not the best way to learn anything. w3schools provide much simpler examples which you can play with to understand the basic concepts, https://www.w3schools.com/css/css_positioning.asp https://www.w3schools.com/css/css_positioning.asp When building more complicated things like menus or cards I like to refer to Bootstrap or the gov.uk design system for examples. I find they get a lot right and both keep things relatively simple.
