# Equalizer (`.sds-loader-equalizer`)

Four bars animate to different heights like an audio equalizer. Loaders animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

## 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-equalizer"><span></span><span></span><span></span><span></span></span>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates movement and scale (transform) — 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.
