YouTube Mobile

Every bottom-nav destination rises through the same soft cross-fade

The tapped thumbnail grows into the player at the top

A Shorts shelf card grows into the full-screen vertical player

A subscription's short grows into the vertical player

A History card resumes the video by growing into the player

Channel avatars push the channel page in from the right

The bell pushes the notification inbox in from the right

Search fades in over the feed in place, with no slide

The create surface rises without carrying the bottom nav

An Up next card grows into the player in place of the video

The channel row under the player drills into the channel

A channel's upload grows into the player; Back shrinks it into place

A notification's small thumbnail expands into the player

An avatar in the inbox pushes its channel one level deeper, same slide
