**Shared element transition（共享元素轉場）** — An element travels and transforms from one position into another, like a thumbnail expanding into a card.
相近術語：
- **Continuity transition**：強調以視覺連續性維持使用者的方位感，是較廣泛的設計概念。
- **View transition**：強調瀏覽器在頁面或狀態間建立轉場；共享元素轉場可以是其中的具體效果。
- **Crossfade**：一張淡出、另一張淡入，沒有同一元素移動與放大的連續感，因此不符合此例。
**Stagger** — Animate several items one after another with a small delay between each, creating a cascade.
複合效果可描述為：**a stagger of Scale in + Fade in entrances**，並以數十毫秒的 **Delay** 進行 **Orchestration**。
- **Scale in** — Element grows from smaller to full size as it appears, often paired with a fade.
- **Fade in** — Element appears by changing opacity.
- **Orchestration** — Deliberately timing multiple animations so they feel like one coordinated motion.
