I'm going to give you an explanation of the best modern football formations. A football formation is a number set that describes the positions of players on the field. It determines how many players play on defense, the midfield, and the frontline. The first number always describes the defender, and so on. For example, a formation like 4-3-3 plays with four defenders, three midfielders, and three forwards. The goalkeeper is never mentioned in a football formation. Most formations are described in three numbers but four- and five-rank formations are also possible. This is created in Proto.io using States and States Animations.

New version to listen to your favourite music. I build this prototype for my (Designing for usability) module at university. It allows you to experience the joy of music in a different, flexible, and adaptable way. This is the first version of Mid-High Fidelity stage of prototyping. Feel free to comment on it, and suggest anything you feel it needs to be added. Thank you.
