## Overview

Rotating Text Badge is the circular "scroll down" or "now booking" badge that sits over the corner of a hero photo, done properly. Your line of text runs around an SVG circle and is fitted to it exactly, so the join between the last word and the first never shows a gap or an overlap, whether the text is twelve characters or forty-eight.

It is built on GSAP ScrollTrigger and InertiaPlugin. The ring turns slowly at rest. Scroll the page and it picks up speed in the direction you are scrolling, with a faint trail behind the letters at speed; stop, and it coasts back down to its idle spin on its own momentum in about a second and a half. Scrolling back the other way slows it through zero rather than snapping round.

Point at the badge and the ring slows almost to a stop, the disc tilts towards the pointer with a soft highlight and a shadow that falls away from it, and the arrow in the middle grows and turns to face the pointer. Press it and the disc squashes and springs back while the arrow shoots out the way it points and comes back in from behind. The demo is one large pink badge over the corner of a photograph; scroll to spin it.

## Features

- Built on GSAP ScrollTrigger and InertiaPlugin: scroll speed adds spin, momentum brings it back to idle
- Text fitted to the circle exactly for any length, re-measured after web fonts load
- Spin follows the scroll direction and passes smoothly through zero when you reverse
- A faint motion trail behind the lettering that only appears at speed
- On hover the ring slows, the disc tilts towards the pointer and the arrow turns to face it
- Press squashes the disc and springs it back; the arrow launches and returns
- A real link or button, named once by its plain text rather than the repeated ring
- Idle speed, scroll boost, direction and separator set by data attributes; colours and size by CSS custom properties
- Small API to set up new badges, refit after a text change, and revert cleanly

## Use Cases

- A "scroll down" or "now booking" badge over the corner of a hero image
- A back-to-top button in a site footer
- An "available for work" sticker on a freelancer's or studio's homepage
- A "new season" or "order now" roundel on a shop's product section

## 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

Your text runs along a circular SVG path. The script works out how many repeats of the text and separator fit around the circle and spreads the small remainder evenly as letter spacing, so every gap, including the one where the ring joins, is the same. It does this again once web fonts have loaded and after a resize.

GSAP ScrollTrigger reads how fast the page is scrolling and the ring eases towards a matching spin. When scrolling stops, GSAP InertiaPlugin takes the spin it had and lets it run down naturally to the idle speed, so the badge seems to have weight. Hover, focus and press are short GSAP tweens with overshoot that always settle back to rest.

The badge is an ordinary link or button with its text written once for screen readers; the ring and the arrow are hidden from them. On touch screens the ring turns only while the page scrolls. With reduced motion the ring stands still, and without JavaScript the badge is a static SVG with real text.

## 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>`:**

_Code snippet omitted: it ships with the download._

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

_Code snippet omitted: it ships with the download._

**3. Add the badge wherever it belongs (a link here; a `<button>` works the same):**

_Code snippet omitted: it ships with the download._

The text inside the `<textPath>` is what visitors see without JavaScript; with it, the script rewrites the ring from `data-rb-label`, so you only need to keep the label up to date.

### Using It With Your Own Design

**What the effect needs from your markup:** a root with `data-rb`, normally the link or button itself. Inside it: `data-rb-label` holding the plain text (visually hidden; it is the accessible name), `data-rb-body` (the disc that tilts and squashes), an `<svg data-rb-ring>` containing a circular `<path>` with a unique `id` and one `<text><textPath>` pointing at it, and optionally `data-rb-icon` around your icon. The icon's first child is what launches on click, so keep the icon wrapped in one element. Give every badge its own path `id`.

**What is only the demo's styling:** the pinned stage with one photograph, the DM Mono face, the pink and ink palette and the badge position. Set the font of the ring with `--rb-font`.

**CSS the effect depends on:** `.rb` needs a size (`--rb-size`) and `position: relative`; `.rb__body` and `.rb__ring` fill it absolutely; `.rb__well` keeps `overflow: hidden` so the arrow can leave and come back in through its edge. The ring's `font-size` attribute is in viewBox units (out of 200), so the badge scales with `--rb-size` without refitting. Change the circle's radius and the script refits to the new length.

| Custom property | Default | Description |
|---|---|---|
| `--rb-size` | `200px` | Diameter |
| `--rb-ink` | `#141412` | Ring text and centre well |
| `--rb-accent` | `#ff3e7f` | Disc and arrow |
| `--rb-disc`, `--rb-text`, `--rb-well`, `--rb-arrow` | from the two above | Override one part on its own |
| `--rb-shadow` | `rgba(0,0,0,.5)` | Disc shadow colour |
| `--rb-focus` | accent | Keyboard focus ring |
| `--rb-font` | DM Mono | Ring typeface |

### Options

| Attribute | Values | Default | Description |
|-----------|--------|---------|-------------|
| `data-rb-speed` | degrees per second | `24` | Idle spin. `0` turns only on scroll |
| `data-rb-boost` | number | `1` | How much scroll speed adds. `0` ignores scrolling |
| `data-rb-reverse` | present | off | Spin anticlockwise; scroll spin mirrors too |
| `data-rb-separator` | any character | `·` | Placed between repeats of the text. Empty for none |
| `data-rb-icon` | `right`, `down`, `left`, `up` or degrees | `right` | The direction your icon is drawn pointing, so it can turn to face the pointer |

### Accessibility

- **Screen readers** hear the label once. The ring, its motion trail and the icon are hidden from assistive technology; the badge's name is the plain text in `data-rb-label`, not the repeated ring.
- **Keyboard:** focusing the badge with the keyboard slows the ring and grows the arrow, as hover does; Enter follows the link and plays the press.
- **Touch:** there is no hover state to stick. A tap squashes the disc and follows the link, and the ring turns only while the page scrolls.
- **Reduced motion:** with `prefers-reduced-motion: reduce` the ring stands still and is still fitted to the circle. Changing the setting while the page is open rebuilds the badge.
- **No JavaScript, or GSAP blocked:** the badge is a static SVG with the real text you wrote in the `<textPath>`.

### Dependencies

**Required:**
- GSAP 3.13+ (the demo is pinned to 3.15.0)
- ScrollTrigger plugin
- InertiaPlugin (free with GSAP since 3.13)

### Browser Support

Current Chrome, Edge, Firefox and Safari. The fit uses SVG letter spacing, which every current engine supports.
