YouTube

YouTube components are the recurring furniture of a channel rather than the video itself: an animated subscribe nudge that presses its own button and rings its own bell, a comment card that features a viewer's reply the way the platform renders it, and an end screen with room for two recommended videos and a channel ring.

Reach for these at the two moments every video has in common — the ask, wherever you put it, and the last twenty seconds. Each one is typed props rather than a template, so a channel's name, handle, avatar and colour are a props change and not a re-export, and the same component renders for a Short at 9:16 without the button sliding under the platform's own UI.
