# Deconstructed Launch Page

> Pinned scroll section where a finished product landing page bursts into a 3D cloud of its own live components (nav, headline words, product photo, feature cards, price and button), then scrolling pulls each part home in captioned chapters until the real, working page is back together.

No performance score is published: it depends on the deployment (server compression, caching, CDN, connection and device) rather than on the code, so measure it where it will live.

## Overview

A complete product launch page appears for a beat, then bursts outward from its call to action into a cloud of its own parts. The navigation, every word of the headline, the product photo, the finish picker, the feature cards, the review, the price and the button all float apart at different depths, each with a soft shadow and a slow drift, while dashed outlines on the page mark where each one belongs.

Scrolling rebuilds the page in five captioned chapters: structure, headline, product, proof and price. Each group flies home to its measured slot, and a fast flick of the wheel lands them with a small overshoot. On a desktop any loose part can be grabbed and thrown; it waits wherever it lands until its chapter calls it home. When the last part settles, the transforms are cleared and the page is ordinary, crisp HTML: the finishes swap the photo, the quantity toggle reprices, Add to bag fills the bag, and Pull it apart starts the show again.

## Features

- Every part is a live DOM component measured from your own layout, so the explosion and the assembly follow whatever page you put inside it
- Group parts into chapters with one data-chapter attribute; each chapter has its own caption and lands in sequence with a stagger
- Headlines split into words with SplitText and scatter as a cascade in reading order, nearest to the viewer
- Projected depth: parts sit at different distances from the camera, with pointer parallax by depth and pre-blurred shadows that rise with height
- A spring follows the scroll, so slow scrolling glides parts home and a fast flick lands them with a velocity-keyed overshoot
- Grab and throw any floating part with Draggable and InertiaPlugin, kept inside the stage; it flies home from where it was left when its chapter arrives
- Settles at no transform at all, so the finished page text is as sharp as a normal page
- Working demo page: finish swatches with a Flip-animated ring, a Flip pair toggle that reprices, Add to bag, and a Pull it apart control
- Phones get a flatter explosion with whole headings as single parts and no dragging; reduced motion shows the finished page with no pin

## Use Cases

- Product launch pages that open by building themselves, so the offer lands at the end of the scroll
- Black Friday and seasonal sale reveals where the price and button are the final chapter
- Agency and studio case studies showing how a landing page was designed, section by section
- SaaS and template marketplaces demonstrating that a page is built from real, reusable components
- Design system and front-end portfolio pages that want a memorable, developer-pleasing opener

## Vibe-Code Ready Setup

This effect includes `START-HERE-AI.md`, a product-specific copy-paste setup prompt for Cursor, Claude Code, ChatGPT, GitHub Copilot, Windsurf, Gemini, and other coding assistants. It tells the assistant to inspect the existing stack, integrate the supplied files, preserve the design, scope selectors, retain accessibility and responsive behaviour, add framework-appropriate GSAP cleanup, and report what it tested.

## How It Works

The page inside the effect is ordinary HTML in its real order, so screen readers and search engines get the finished content throughout. On load the script measures where every marked part sits in that layout, then generates an exploded position for each: an offset away from the centre of the page, a distance from the camera and a tilt. Large parts sit further back and small ones come forward, passes push apart any parts that would bury each other, and of eight seeded layouts the two with the least overlap are kept and alternate on each replay.

ScrollTrigger pins the section and maps the scroll to five chapters. Each part has a target between exploded and home, and a spring follows it, which gives the glide on slow scrolls and the overshoot on fast ones. Each frame projects the part through the camera so nearer parts move and scale more, and its shadow rises with it. Everything is re-measured whenever the layout changes, so parts never fly home to an old position, and once a part is home its transform is removed entirely.

## Documentation

How this effect works and how it goes into a page. The reference you use once you own the files (worked examples, events, the programmatic API, the class list) ships with the download.

### Quick Start

**1. Add to your HTML `<head>`:**

_In your download: the working code for this step, in `index.html`._

**2. Add the section to your `<body>`.** Put your page inside `[data-dlp-page]` and give each part a chapter number:

_In your download: the working code for this step, in `index.html`._

**3. Add before the closing `</body>` tag:**

_In your download: the working code for this step, in `index.html`._

The script mounts every `[data-dlp]` section once the web fonts load (or after 600ms at most), pins it for the configured runway and releases it once the page is assembled. The opening burst then runs on a fixed clock: the button presses, a ring leaves it, the page detonates past its spots and settles, and the dashed slots draw in. A font that arrives late only triggers a re-measure.

The demo's faces (Instrument Serif and Instrument Sans, SIL Open Font License 1.1) are self-hosted in `assets/fonts/` and preloaded in the `<head>`, so the headline is set in its own face before it splits; `assets/fonts/OFL.txt` holds the licence and copyright notices. Self-hosting or preloading your own display face matters here for the same reason: a late font swap reflows the page the visitor has just seen.

### Using It With Your Own Design

**What the effect needs from your markup:**

- A root `[data-dlp]` and, inside it, one `[data-dlp-page]`. The page element is the positioning context for the parts and the generated slots and shadows, and it is the layer the camera zooms.
- `data-chapter="n"` on each part, starting at 1. Parts in a chapter land together, staggered in document order. Mark the visual blocks a visitor would recognise (a card, a button, a photo, a heading), not every span. Aim for about 24 parts or fewer.
- **Parts must not be nested** inside other parts, and must not rely on a CSS `transform` for positioning: the script owns each part's transform. Position with insets, margins, flex or grid instead.
- `data-dlp-split` on a heading splits it into words (desktop only) that fly as separate parts in reading order. On phones the heading stays one part.
- `data-dlp-origin` on one element sets where the opening burst starts from. Without it, the last part bursts first.
- The caption bar is optional. `[data-dlp-steps] > li` gets `is-active` for the current chapter, `[data-dlp-cue]` before the first chapter, `[data-dlp-done]` when the page is assembled, and each `[data-dlp-meter] > i` gets a `--fill` value from 0 to 1. `[data-dlp-reset]` is shown when the page is assembled.

**What is only the demo's styling:** everything prefixed `.lp-` in `style.css` (the lamp brand page, its fonts, palette and photos), the construction grid on the ground, and the look of the caption bar. The `mountDemoPage` function at the end of `script.js` (finish swatches, quantity toggle, Add to bag) is demo behaviour too; delete it with the demo page.

**CSS the effect depends on** (marked REQUIRED in `style.css`):

- The root is one viewport tall with `overflow: hidden`, so the cloud never causes page scroll.
- `[data-dlp-page]` is `position: relative` with `isolation: isolate`, so floating parts can stack above one another by depth.
- `:where(.dlp [data-chapter])` gives parts `position: relative` and a z-index above the generated `.dlp__slot` and `.dlp__shadow` layers. It has zero specificity, so your own `position: absolute` still wins.
- `.dlp.is-live .dlp__page` drops the page background while the effect runs; the generated `.dlp__fill` fades the paper back in as chapter 1 lands. If you change the page colour, change `.dlp__fill` to match.
- `.dlp__flash` is the ring that leaves the burst origin, and `.dlp.is-celebrating` is set for about a second when the last part lands (the demo uses it for a sheet lift, a shine across the button and a meter sweep). Restyle or drop both freely.

### Options

Set these on the `[data-dlp]` root.

| Attribute | Values | Default | Description |
|-----------|--------|---------|-------------|
| `data-spread` | `0` to `2.5` | `1` | How far parts travel from their slots |
| `data-depth` | `0` to `2` | `1` | Depth range of the cloud: nearer parts scale and parallax more |
| `data-runway` | Pixels | `2800` | Scroll distance for the full assembly on screens 768px and wider |
| `data-mobile-runway` | Pixels | `2000` | Scroll distance on phones |
| `data-reexplode` | `true`, `false` | `true` | `false` keeps landed parts home when the visitor scrolls back up |
| `data-drag` | `true`, `false` | `true` | Grab and throw floating parts (fine pointers only) |
| `data-intro` | `true`, `false` | `true` | Show the finished page, then burst it apart on load. `false` starts already exploded |
| `data-split` | `true`, `false` | `true` | Allow `data-dlp-split` headings to split into words |
| `data-seed` | Integer | `11` | Base seed for the exploded layout. Eight layouts are tried from it, scored by how much parts overlap (text over text counts triple), and the two cleanest alternate on each Pull it apart |
| `data-dlp-static` | `0` to `1` | none | Freeze at this scroll progress with no pin, drift or intro (posters and screenshots) |

### Accessibility

- **Real content throughout.** The page is ordinary HTML in its real reading order. Parts only ever move with transforms, so screen readers, search engines and find-in-page get the assembled content at every scroll position. Split headings keep an accessible label from SplitText.
- **Reduced motion.** With `prefers-reduced-motion: reduce` there is no pin, no explosion and no caption bar: the finished page is shown immediately and every control works. Switching the preference while the page is open rebuilds the effect in place.
- **Keyboard.** All controls are native buttons and links with visible focus. Tabbing to a floating part calls it home, and keyboard activation always goes through, even while the part is still flying in. A floating part ignores pointer clicks until it is home, so a stray click during the show cannot add to the bag. After **Pull it apart**, focus moves to the section so keyboard users stay in place.
- **Touch.** Phones get a flatter explosion with whole headings as single parts, no dragging (touch scrolls the page as normal) and the same chapter captions.
- **No JavaScript.** Without the script, or if a required CDN file fails, the page is simply shown assembled.

### Dependencies

**Required:**
- GSAP 3.13+ (the demo is built against 3.15.0; `SplitText.create` and the public SplitText and InertiaPlugin builds need 3.13)
- ScrollTrigger

**Optional, each feature switches off cleanly without its plugin:**
- SplitText (headline words as separate parts)
- Draggable and InertiaPlugin (grab and throw)
- Flip (the demo page's swatch ring and quantity toggle)
- Lenis 1.3+ (smooth scrolling)
