# Push In

A centered headline gains focus through one slow, continuous camera push and a gentle fade out.

**Push In**

```html push-in.html theme={null}
<!doctype html>
<!--
  push-in: HyperFrames video primitive (camera / holdable / emphasize)

  Concept: a centered headline stays composed while the full stage makes one
  slow camera push. The intensity variable owns the final scale, and a soft
  vignette keeps attention on the subject.

  Variables:
    - text (string, default "Focus"): the centered headline.
    - intensity (subtle | standard | bold, default "standard"): maps to a
      final stage scale of 1.08, 1.12, or 1.18.

  Envelope: fixed 0.80s IN eases the camera into motion, elastic HOLD carries
  a continuous linear creep, and fixed 0.65s OUT gently fades the completed
  push. If the duration is shorter than IN plus OUT, both fixed phases
  compress proportionally and HOLD becomes zero. Longer durations stretch
  HOLD only, so the same total camera travel happens more slowly. The
  timeline is never time-scaled.

  Mount contract: the runtime clones only this template. #root fills the
  host box, establishes the container query basis, has no data-width or
  data-height, and registers one paused timeline under the hardcoded push-in
  id.

Copy npx hyperframes add push-in to the clipboard

That writes one file: `compositions/components/push-in.html`.

## Paste it into your composition

Open `compositions/components/push-in.html` and copy what is inside into your own composition.

A component has no size or duration of its own. It takes both from the composition
you paste it into.

## Variables

Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:

| Variable | Default | Accepts | What it does |
| - | - | - | - |
| `text` | `Focus` | string | Text centered in the camera frame. |
| `intensity` | `standard` | `subtle`, `standard`, `bold` | Final camera scale reached by the push. |

Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:

```html wrap theme={null}
<div
  data-composition-id="push-in"
  data-composition-src="compositions/components/push-in.html"
  data-variable-values='{"text":"Focus","intensity":"standard"}'
></div>
```

Tagged `motion-primitive` `camera` `push-in` `focus` `emphasize` `holdable`.
