# Perspective Marquee

A 3D tilted marquee with depth feel as items roll toward the horizon.

**Perspective Marquee**

```html perspective-marquee.html
<!--
  Perspective Marquee - typography primitive for HyperFrames.

  Paste the markup and CSS into a composition. Drive the timeline integration
  from a paused GSAP timeline so renders remain deterministic.

  Variables. The script reads each one, falls back to the declared default on
  anything missing or unrecognised, and writes the result as a custom property
  the CSS above consumes. The timeline recipe below is untouched by them: it
  keeps driving one horizontal offset, and these decide how far that offset
  carries and what the strip looks like while it rolls.

    - tilt (flat | standard | steep, default standard): how far the marquee
      plane leans back toward the horizon. flat is almost head-on, steep sends
      the strip deep into the frame.
    - travel (short | standard | long, default standard): scales the offset the
      timeline drives, so the strip covers a shorter or longer run in the same
      time. short reads as a slow drift, long as a fast roll.
    - tone (ink | paper | accent, default ink): pill colour. ink is near-black
      with white type for light frames, paper near-white with dark type for
      dark ones, accent rides the brand token.
    - words (string, default COMPONENTS, PRIMITIVES, TRANSITIONS, AGENTS): the
      comma separated list of pill labels. The list is laid down twice so the
      strip still reads as a continuous loop.

  On every default the result is identical to the original: four near-black
  pills, laid down twice, rolling 360px left across an 18 degree tilt.

That writes one file: `compositions/components/perspective-marquee.html`.

## Paste it into your composition

Open `compositions/components/perspective-marquee.html` and copy what is inside into your own composition.
The file opens with a comment header that walks you through it.

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 |
| - | - | - | - |
| `tilt` | `standard` | `flat`, `standard`, `steep` | How far the marquee plane leans back toward the horizon. |
| `travel` | `standard` | `short`, `standard`, `long` | Scales the offset the timeline drives, so the strip covers a shorter or longer run in the same time. |
| `tone` | `ink` | `ink`, `paper`, `accent` | Pill colour: ink for light frames, paper for dark ones, accent rides the brand token. |
| `words` | `COMPONENTS, PRIMITIVES, TRANSITIONS, AGENTS` | string | Comma separated pill labels. The list is laid down twice so the strip still reads as a continuous loop. |

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
<div
  data-composition-id="perspective-marquee"
  data-composition-src="compositions/components/perspective-marquee.html"
  data-variable-values='{"tilt":"standard","travel":"standard","tone":"ink","words":"COMPONENTS, PRIMITIVES, TRANSITIONS, AGENTS"}'
></div>
```
