# Ink Stroke (`.sds-input-ink`)

Outline expands with ink-stroke feel. Inputs animation in SDS Motion Forge v5.0.0. It plays once as soon as the class is applied.

- Category: Inputs (https://sds-motion-forge.netlify.app/categories/inputs/)
- Animated properties: outline-color, outline-offset
- Compositor-only: no
- 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/inputs.min.css" />

<input class="sds-input-ink" placeholder="Type here" />
```

## How it works

Plays when the field receives focus. It animates an expanding outline. `--sds-duration-instant` controls the speed — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).
