# Wordmark Dock Preloader

> A preloader where your brand wordmark fills the screen, its letters rising through a mask one by one, then the whole mark shrinks and flies into the header's logo slot as the page arrives around it.

## Overview

Most preloaders put a logo on an overlay, fade it out, and leave a second copy of the same logo waiting in the header. This one has only one logo. Your header wordmark, live text or your own SVG, grows to fill the width of the screen and its letters rise into view through a mask, one after another. When the page is ready, the whole mark shrinks and flies into its own slot in the header, and the navigation, headline and hero arrive around it as the cover draws up behind the flight.

Because the giant mark and the header logo are the same element, there is no swap and no flicker at the end: the loader simply becomes the masthead. The fit is measured, so a five-letter name and a fifteen-letter name both fill the screen edge to edge, and the mark lands exactly where your header puts it, whatever the layout.

It waits on real readiness, with a minimum hold so the wordmark always reads and a hard cap so nobody waits on a slow image. Repeat visitors in the same session can skip it, and it degrades to a short cover fade for reduced motion and a plain header without JavaScript.

## Features

- One logo, not two: the header wordmark itself becomes the giant intro mark and docks back into place
- Letters rise through individual masks, with element children such as an SVG mark or a coloured dot kept whole
- Fitted to the viewport by measurement after fonts load, so short and long brand names both fill the width
- Lands on the header slot's real position with the Flip plugin, wherever your layout puts the logo
- Waits for fonts and page load, with a minimum hold and a hard cap, and an accent hairline that shows the wait
- Page content marked for reveal arrives around the docking mark; images can open with a clip from below
- Once-per-session mode, replay(), pause() and play() to hold the sequence, and a wordmarkdock:complete event
- Reduced motion keeps the logo in the header and fades the cover; no JavaScript shows a normal header

## Use Cases

- Studio and agency sites where the brand name is the first and strongest thing on the page
- Product and furniture brands with a distinctive wordmark set in a characterful face
- Launch pages that want a branded opening without a separate splash logo
- Portfolio sites whose header logo should feel earned rather than simply present
- Multi-page sites that play the intro once per visit and open later pages straight onto the header

## 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, 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 cover is an ordinary layer over a complete page, so search engines and visitors without JavaScript get the full HTML and a normal header. When the script starts, it takes the logo already sitting in your header, lifts it above the cover and scales it about its centre until it spans the screen. The size adapts to your actual logo in its actual typeface, waiting for webfonts first, which is why any brand name fills the width without guesswork.

Each letter sits in its own clipping mask and rises into view in a quick stagger. The mark then holds until the page reports ready, never shorter than the minimum and never longer than the cap, while a thin accent line underneath tracks the wait.

The dock is the signature. The Flip plugin records the giant mark, lets it settle back into its header slot, and animates the difference, so the logo shrinks and travels along one continuous path into exactly the place your layout gives it. The cover draws up behind the flight, the navigation and copy rise in, and the hero image opens from below. At the end the letters are joined back into the original text, so the header holds the same logo it started with.

## 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. In the `<head>`, before your stylesheet:**

_Code snippet omitted: it ships with the download._

**2. The cover goes first in `<body>`; mark your header logo:**

_Code snippet omitted: it ships with the download._

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

_Code snippet omitted: it ships with the download._

The script starts itself. Copy the **Effect** block from the top of `style.css` (or the whole file while you try it).

### Using It With Your Own Design

**The logo.** `data-wd-target` is a CSS selector for the element that becomes the giant mark; it defaults to `[data-wd-mark]`. Point it at the wordmark itself, not at a padded link around it: the fit measures that element's box. It can hold:

- **Live text.** Each character rises in its own mask. At the end the characters are joined back into the original text nodes, so kerning and selection behave normally in the header.
- **Element children.** Any child element (an inline SVG, an icon, a styled dot such as the demo's `<span data-mark=".">`) is kept whole and rises as one letter. For an SVG logo, give each letter its own child element, or use one `<svg>` and it rises as a single piece.

An inline element is made `inline-block` for the run only, because it has to be transformed. Give the logo its colour from `--wd-ink` so the giant and docked states match.

**Stacking.** The cover sits at `z-index: var(--wd-z)` (1000). The logo is lifted one above it with `position: relative` and a `z-index` for the run. If your header creates its own stacking context (a sticky or fixed header with a `z-index`, a `transform`, a `filter`), the logo cannot escape it: put `data-wd-lift` on the header and the header is lifted instead. Give a lifted header a transparent or cover-coloured background, or set `--wd-cover` to match it.

**Reveal targets.** Anything with `data-wd-reveal` is hidden while the cover is up (by the `html.wd-lock` rule in the CSS) and rises in as the mark docks. `data-wd-reveal="clip"` opens the element from below instead, which suits images. When the sequence ends their inline `opacity`, `visibility`, `transform` and `clip-path` are cleared, so do not rely on inline values for those properties on reveal targets.

**What is only the demo.** Halden, Gloock and Mona Sans, the photographs, the header, nav, hero layout and the Replay button styling. The progress hairline is optional: delete the `data-wd-progress` element and nothing else changes.

**Colours and timings:**

| Property | Default | What it controls |
|---|---|---|
| `--wd-cover` | `#f4f4f2` | Cover ground |
| `--wd-ink` | `#141412` | Wordmark colour (applied by your logo CSS) |
| `--wd-accent` | `#0b8457` | Progress hairline (and, in the demo, the dot) |
| `--wd-z` | `1000` | Cover stacking order |
| `--wd-min` | `1.2` | Minimum hold, seconds |
| `--wd-max` | `4` | Hard cap, seconds |
| `--wd-rise` | `0.9` | Letter rise, seconds |
| `--wd-dock` | `1.1` | Flight into the header, seconds |

### Options

Data attributes on the `[data-wd]` element override the CSS timings.

| Attribute | Default | Description |
|---|---|---|
| `data-wd-target` | `[data-wd-mark]` | Selector for the header logo |
| `data-wd-min` | `1.2` | Shortest hold in seconds, so a cached load still reads. `0` is allowed |
| `data-wd-max` | `4` | Hard cap in seconds: the mark docks by then whatever is still loading |
| `data-wd-rise` | `0.9` | Letter rise duration |
| `data-wd-dock` | `1.1` | Dock flight duration |
| `data-wd-fit` | `0.9` | Share of the viewport width the giant mark fills (0.2 to 1) |
| `data-wd-once` | off | Skip the sequence once it has played this session. A value names a separate session key; empty uses the site-wide key |

Other hooks: `data-wd-mark` (default logo hook), `data-wd-lift` (stacking escape, above), `data-wd-progress` (hairline), `data-wd-reveal` / `data-wd-reveal="clip"` (page content), `data-wd-replay` (any button that replays).

**What "ready" means.** The giant mark docks when all of these hold: the letters have risen, the minimum has passed, the logo's webfont has loaded and the document has finished loading (`window` load, so images included). The cap overrides readiness. The hairline climbs toward 90% on time alone and only completes when the page is ready.

**Once per session.** Every completed run records itself in `sessionStorage` (under the site-wide key unless `data-wd-once` names one). A page with `data-wd-once` then opens with no cover. Storage that is blocked just means the sequence plays.

### Accessibility

- The cover is `aria-hidden` and holds nothing focusable, so it never traps focus. The logo link is not clickable while giant.
- While the letters are split, a visually hidden copy of the text keeps the logo readable to screen readers; the masks are hidden from them.
- All content is in the HTML from the start: the cover is only a layer, so crawlers and assistive technology read the full page.
- Scroll is locked only while the cover is up.

#### Reduced Motion Behavior

The logo stays in its header slot, lifted above the cover, and the cover fades out over 0.4s once the logo's font is ready. No travel, scaling or masking. A preference change mid-sequence settles the page cleanly.

#### Without JavaScript

The cover is `display: none` unless `has-js` is present, and the script removes `has-js` if GSAP or Flip fails to load. As a last resort the cover hides itself after six seconds if the script never starts.

### Dependencies

**Required:**
- GSAP 3.12+ (the demo pins 3.15.0)
- Flip plugin

No other plugins and no Lenis.
