# Guillotine (`.sds-btn-guillotine`)

The top half drops onto the emerging bottom half with a landing squash. Buttons animation in SDS Motion Forge v5.0.0. It plays once as soon as the class is applied.

- Category: Buttons (https://sds-motion-forge.netlify.app/categories/buttons/)
- Animated properties: clip-path, 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/buttons.min.css" />

<button class="sds-btn-guillotine">Button</button>
```

## How it works

Plays once, as soon as the class is applied. It animates a clip-path mask, opacity and movement and scale (transform) — compositor-only, so it never causes page reflow. `--sds-duration-base` controls the speed and `--sds-ease-emphasized` controls the feel — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).
