# Gate Open (`.sds-input-gate-open`)

Two tinted panels part horizontally over the field when it takes focus. Inputs animation in SDS Motion Forge v5.0.0. It plays once as soon as the class is applied.

- Page: https://sds-motion-forge.netlify.app/animations/input-gate-open/
- Category: Inputs (https://sds-motion-forge.netlify.app/categories/inputs/)
- Animated properties: opacity, transform
- 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/inputs.min.css" />

<div class="sds-input-gate-open">
  <input placeholder="Type here" />
</div>
```

## How it works

Plays when the field receives focus. It animates opacity and movement and scale (transform) — compositor-only, so it never causes page reflow. `--sds-duration-fast` controls the speed and `--sds-ease-decelerate` controls the feel — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).
