# Idle Glow (`.sds-card-idle-glow`)

Drop-shadow glow breathes in and out on a 2.8 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
- 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-idle-glow">Card</div>
```

## How it works

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