HYEREE AHN~ This main lecture is designed to teach you how to create a full page, countup, animation that runs when active, GNB MenuBar, etc. If you want to study responsiveness, you can take the DobdaApplication or Musein lecture. And the video was edited quickly on purpose to eliminate boredom. Online lectures have the advantage of being able to be listened to repeatedly~~ Have a good day today~ J.young Dream
