I like the visual approach, its super bubbly, which is very nice to see, as nowadays everyone tries to look basically like the next designer. I like the animation, though you have hardware acceleration issues on chrome; the footer blinks when you interact with the icons below, that happens because they are not on their own rendering layer. Try working with will-change and the contain property, to solve this.

then you have this selector: .view>*.current, which is super weird, as it is exactly the same as writing .view > .current, as both select any direct child from .view with the class .current. Did you write the css yourself?
