`zoom` 用于元素的 **移除与添加**。

```jsx
const [cards, setCards] = useState(["1"])
const cardDuplicated = [...cards]

const handleRemove = (id) => {
  cardDuplicated.splice(cardDuplicated.indexOf(id), 1)
  setCards(cardDuplicated)
}

const handleAdd = () => {
  cardDuplicated.push(Math.random().toString(36).substring(3, 8))
  setCards(cardDuplicated)
}

return (
  <div style={{ width: "80%" }}>
    <Motion transition="zoomHorizontal">
      {cards.map((c, i) => (
        <div
          key={c}
          style={{
            paddingBottom: "20px",
            display: "inline-block",
            verticalAlign: "top",
          }}
        >
          <Card className="adui-motion-card" style={{ width: "200px" }}>
            <Card.Header title={`卡片${i}`} />
            <Icon icon="cancel" size={24} onClick={() => handleRemove(c)} />
          </Card>
        </div>
      ))}
    </Motion>
    <div className="adui-motion-example-add" onClick={handleAdd}>
