# Label Wave (`.sds-btn-label-wave`)

Label pieces ripple a 2px wave left to right with tiny rotations. Buttons 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/buttons.min.css" />

<button class="sds-btn-label-wave"><span>→</span> <span>Button</span></button>
```

## 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. `--sds-duration-slower` controls the speed — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that). The animation runs on the element's direct children — it needs child elements to be visible.
