# Night Sweep (`.sds-btn-night-sweep`)

A dark veil wipes off to reveal the lit button, rests, then falls again. Buttons animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

- Page: https://sds-motion-forge.netlify.app/animations/btn-night-sweep/
- Category: Buttons (https://sds-motion-forge.netlify.app/categories/buttons/)
- Animated properties: clip-path, opacity
- 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-night-sweep">Button</button>
```

## How it works

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