# Line-by-Line Slide

Each line enters from the left with staggered slide and exits to the right.

**Line-by-Line Slide**

```html line-by-line-slide.html
<!--
  Line-by-Line Slide - 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 a custom property the CSS above
  consumes. The timeline recipe below is untouched by them: it keeps driving
  one sideways offset, and direction decides which way that offset points.

    - size (compact | standard | display, default standard): type size of the
      stack, 40px, 52px, or 68px.
    - tone (ink | paper | accent, default ink): line colour. ink is near-black
      for light frames, paper near-white for dark ones, accent rides the
      brand token.
    - density (fine | standard | coarse, default standard): the gap between
      lines, 4px, 10px, or 20px.
    - direction (left | right, default left): which side the lines slide in
      from. left keeps the original entry, right mirrors it.

  On every default the result is identical to the original: near-black 52px
  lines, 10px apart, entering from the left.

Copy npx hyperframes add line-by-line-slide to the clipboard

That writes one file: `compositions/components/line-by-line-slide.html`.

## Paste it into your composition

Open `compositions/components/line-by-line-slide.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 |
| - | - | - | - |
| `size` | `standard` | `compact`, `standard`, `display` | Type size of the whole stack. |
| `tone` | `ink` | `ink`, `paper`, `accent` | Line colour: ink for light frames, paper for dark ones, accent rides the brand token. |
| `density` | `standard` | `fine`, `standard`, `coarse` | The gap between lines, from a tight block to an airy stack. |
| `direction` | `left` | `left`, `right` | Which side the lines slide in from as the timeline drives the offset. |

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="line-by-line-slide"
  data-composition-src="compositions/components/line-by-line-slide.html"
  data-variable-values='{"size":"standard","tone":"ink","density":"standard","direction":"left"}'
></div>
```

{/* hf:generated-footer */}
