# Glass Frost (`.sds-card-glass-frost`)

Blur + brightness frost cycle — card appears to ice over and clear on a 3.5 s loop. Cards animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

- Category: Cards (https://sds-motion-forge.netlify.app/categories/cards/)
- Animated properties: filter, 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/cards.min.css" />

<div class="sds-card-glass-frost">Card</div>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates filters (blur/brightness) and opacity — 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.
