# Signal Bars (`.sds-loader-signal`)

Signal Bars — loader animation. Loaders animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

- Animated properties: opacity
- Compositor-only: yes
- Needs child elements: yes
- 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/loaders.min.css" />

<span class="sds-loader-signal"><span></span><span></span><span></span><span></span></span>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates 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. The animation runs on the element's direct children — it needs child elements to be visible.
