# Stack Drop (`.sds-card-stack-drop`)

Entrance: card drops from 38 px above with a two-stage deceleration brake. Cards animation in SDS Motion Forge v5.0.0. It plays once as soon as the class is applied.

- Page: https://sds-motion-forge.netlify.app/animations/card-stack-drop/
- Category: Cards (https://sds-motion-forge.netlify.app/categories/cards/)
- Animated properties: filter, opacity, transform
- Compositor-only: yes
- Needs child elements: no
- Needs per-character spans: no
- JavaScript: none required

## Use it

```html
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@salkomdesignstudio/sds-motion-forge/dist/categories/cards.min.css" />

<div class="sds-card-stack-drop">Card</div>
```

## How it works

Plays once, as soon as the class is applied. It animates filters (blur/brightness), opacity and movement and scale (transform) — compositor-only, so it never causes page reflow. Timing is fixed for this effect, but you can still override animation-duration/timing-function on the element.
