Hello, I work as a back-ene developer, I decided to experiment a little with front-end design. The best way to learn is to create a clone of some quality product, I decided to make a copy of the site britvabarber.ru, you can say that google (technology) to do something like that. It is especially interesting how video playback in the background is implemented. thank.
