You have a site. Now make it yours.
An AI build hands you a front end and stops there. No CMS, no client login, no real ownership: you cannot hand it over, and you cannot change it without going back and re-prompting. UiChemy turns that build into native, editable WordPress you own, in the builder you already use.

What does the Outerglow Music & Arts Festival prompt build?
A vibrant festival landing page with bold typography, neon colors, and immersive animations. Showcase performers, stages, event schedules, and ticket options through interactive sections that capture the energy of a live
Which AI tools does the Outerglow Music & Arts Festival prompt work with?
It's written for Claude. Paste the whole prompt into Claude and it builds the complete site for you, then bring the result into WordPress with UiChemy. This prompt also has a WordPress version: with the UiChemy MCP connected, Claude builds the page straight into WordPress.
How do I turn the result into a WordPress site?
After the AI builds your site, UiChemy Composer rebuilds it as native, editable WordPress in Elementor or Gutenberg (Bricks coming soon) — you own it and edit it in your builder. See AI to WordPress.
Is the Outerglow Music & Arts Festival prompt free?
Yes — it's free to copy, no account needed.
Can I edit the website after it's built?
Yes. Once it's in WordPress with UiChemy, every section is native and editable — no re-prompting, no lock-in.
Outerglow Music & Arts Festival · Section prompt
# MASTER PROMPT — Outerglow — Music & Arts Festival · v2
### Plain HTML, CSS and JavaScript. No WordPress, no page builder, no framework, no build step.
## ▶ HOW TO USE THIS PROMPT
**Paste this whole document into Claude. Nothing to attach.** It carries the complete source of the site plus the address of every image, so Claude can assemble a folder that owns its own assets and hand it back as a zip.
**INSTRUCTION TO CLAUDE — BUILD IT, DO NOT ASK.** Every decision is already made in this document. Do not stop to ask the user questions, do not offer options, and do not ask for confirmation before starting. Write the files, zip them, hand over the archive, then report what you built.
1. Create a folder named `outerglow` and write out every file in the appendix below **exactly as written** — do not reformat, rename, shorten, reorder or "improve" anything.
2. **Download the 22 images and 3 fonts into `assets/`.** The code already points at `assets/…` — nothing in it references a remote host. Run this from inside the folder; the commands correspond to the ASSET MANIFEST below:
```bash
mkdir -p assets

curl -fsSL 'https://demo.uichemy.com/wp-content/uploads/2026/09/outerglow__images-prog-talks.jpg' -o 'assets/prog-talks.jpg'
```
Then check every file arrived and none is a zero-byte or HTML error page:
```bash
ls assets | wc -l # expect 25 files
find assets -size -1k # expect no output
```
If any download fails, retry it — the host is occasionally slow. Do **not** fall back to hotlinking the remote URL: the whole point is a folder that works offline.
3. **Zip that folder and give the user the archive.** Its contents:
```
outerglow/
index.html
css/style.css
js/clock.js
js/core.js
js/hero.js
js/lineup.js
js/main.js
js/particles.js
js/programme.js
js/ring.js
js/vendor/CustomEase.min.js
js/vendor/Flip.min.js
js/vendor/ScrollTrigger.min.js
js/vendor/gsap.min.js
js/vendor/lenis.min.js
js/vendor/three.min.js
assets/
anybody-var.woff2
schibsted-grotesk-var.woff2
spline-sans-mono-400.woff2
artist-01.jpg
… 21 more images
```
```bash
zip -r outerglow.zip outerglow -x '*.DS_Store'
```
Then hand over `outerglow.zip` as a file the user can download, not as text in the chat.
4. Before handing it over, serve the folder and confirm it runs:
```bash
cd outerglow && python3 -m http.server 8000 # then open http://localhost:8000
```
Check the page renders, images and fonts load from local files with external networking disabled, and scrolling drives the animations. Test at 390, 768, 1024, 1440 and 2560 px wide; also inspect 320 px and phone landscape. Exercise navigation, programme filters, set-info expansion, packing-item interactions and the clock. Report the known source limitations below honestly.
The finished folder needs no network for its images — they are in `assets/`.
Do not rebuild the design from the description below. The description is there so a person can understand and edit the code. The appendix is the deliverable.
---
## ▶ WHAT YOU GET
Outerglow is a lakeside music and arts festival: three days, four stages, dawn swims and no VIP. The page promotes 13–15 August 2027 at Lake Veldmoor.
**16 code files plus an `assets/` folder holding 22 images and 3 fonts, delivered as `outerglow.zip`.**
| File | What it is |
|---|---|
| `index.html` | Full page markup, content, navigation and SVG decorations |
| `css/style.css` | Design tokens, variable typography, layout and responsive styles |
| `js/core.js` | Shared helpers, easing, motion preferences and smooth scrolling |
| `js/hero.js` | Stepped pixel mask, intro and breathing wordmark |
| `js/particles.js` | Four procedural particle stage emblems and scroll morphs |
| `js/lineup.js` | Pixel transitions, rolling numerals, set notes and photo strips |
| `js/programme.js` | Marquees, category filters and animated reflow |
| `js/ring.js` | Orbiting packing items, hover descriptions and list download |
| `js/clock.js` | Festival-time dial and live countdown |
| `js/main.js` | Boot sequence, navigation, menu and footer behavior |
| `js/vendor/` | Six bundled dependency files: GSAP, ScrollTrigger, CustomEase, Flip, Lenis and Three.js |
**Six main sections:** `#top` · `#stages` · `#lineup` · `#programme` · `#pack` · `#tickets`, with a header/menu, footer and fixed festival clock.
---
## ▶ WHAT CHANGED IN V2
This revision includes the approved supporting-label typography update and organizes the prompt for straightforward reuse. The visual design and source interactions remain intact.
- **Natural mixed-case labels.** The header date/location, hero metadata, tagline and fixed clock/countdown no longer force all capitals.
- **Normal letter spacing.** Those same labels use normal tracking instead of the spaced-out uppercase treatment.
- **Exact wording retained.** Examples: “13–15 Aug 2027 · Lake Veldmoor · 4 stages”, “Dance till the lake turns pink.”, “Gates open in” and “Fri”.
- **Display wordmarks retained.** The large Outerglow lettering keeps its original styling and animation.
- **Complete source retained.** The appendix contains all 16 code files, including the typography override. No attachment or remembered conversation is required.
This is not a responsive-repair revision. Known source limitations are listed below.
---
## ▶ WHERE THE MEDIA COMES FROM
All **22 images and 3 fonts** must live in a flat `assets/` folder inside the delivered ZIP. The HTML, CSS and JS already use relative paths (`assets/…` or `../assets/…` as appropriate).
Download them once at build time from the WordPress Media Library URLs in the manifest. Those URLs are transport only: the finished folder must not depend on the media host. The six vendor libraries are also included in the appendix and must remain local. No Google Fonts request is needed.
Keep original asset bytes and filenames. Retry failed downloads and reject empty files or HTML error responses; do not replace missing files with hotlinks or generated substitutes.
---
## ▶ HOW THE MOTION IS PUT TOGETHER
- The hero opens through a stepped mask and contracts as the visitor scrolls. Its wordmark animates the variable font’s width axis.
- The stages use seeded particle geometry for a sun, reeds, pier and crescent. Scroll progress drives the morph and chapter changes.
- The line-up combines photo parallax, pixel dissolves, rolling day numerals, row reveals, expandable set notes and looping photo strips.
- The programme combines drifting image rails with category filtering and Flip-based reflow.
- Packing items orbit in two tilted rings, react to scroll and expose short descriptions on hover, focus or tap.
- The clock maps page progress to festival time while the countdown uses the real date.
Preserve dependency order and the source’s `?skip-intro`, `?static` and reduced-motion paths. Preserve all copy, timings, prices and seeded randomness. Do not substitute different effects.
---
## ▶ DESIGN TOKENS
The source stylesheet defines the palette, fonts, spacing and easing with custom properties:
- `--glow`: `#FF00B8`; `--acid`: `#C6FF00`; `--black`: `#000000`; `--white`: `#FFFFFF`, plus their opacity variants.
- `--f-title`: Anybody; `--f-ui`: Schibsted Grotesk; `--f-mono`: Spline Sans Mono. All three font files are supplied in the media manifest.
- `--gutter`: `clamp(16px, 2.2vw, 32px)`; `--head-h`: `64px`, changing to `56px` on phones.
- `--og`: `cubic-bezier(.625, .05, 0, 1)`; `--clock-safe`: the fixed-clock clearance token.
Keep the approved mixed-case override at the end of `css/style.css`.
---
## ▶ WHAT THIS PROMPT DELIBERATELY DOES NOT CONTAIN
- No WordPress, page builder, builder wrappers or compatibility styles in the delivered site.
- No framework, TypeScript, bundler, package installation or build step.
- No CMS, payment flow, mailing-list integration or server backend.
- No runtime dependency on an external image, font or JavaScript host.
Deliver the actual `outerglow.zip` file after verification, not a code-only chat response or an implementation plan.
---
## ▶ KNOWN SOURCE LIMITATIONS
Preserve the supplied design and report these issues rather than claiming universal responsiveness:
- Long Programme and Wristbands menu labels can clip on mobile/tablet.
- The mobile menu can exceed the available height in landscape.
- The Programme heading can overlap its image column at tablet widths.
- A photo-caption container can overflow at 320 px; the fixed clock can compete with hero actions in narrow views.
Ticket-choice, newsletter, volunteer and press links are demo anchors. There is no checkout, payment processing, newsletter service or contact backend. The packing-list download is a client-generated text file.
Verify the resulting build in a browser and report unavailable checks. Matching source behavior does not constitute physical-device or cross-browser certification. Do not redesign or silently repair these unrelated issues during reproduction.

/* Signature · "sun ring" festival clock + live countdown
Page scroll 0 → 1 maps to festival time Friday 12:00 → Monday 04:00 (64 h).
The dial is a 24 h face (00:00 at the top, clockwise). It shows the hour (the sun dot), the sunset tick at 21:12,
and one arc per stage for its daily hours, lit when that stage is live. Clicking jumps to the line-up row that
is playing at that hour. The countdown to gates (Fri 13 Aug 2027, 14:00 CEST) runs from the real clock. */

- The mask outline lives on a grid of 18 columns × 12 rows → cells 80 × 75 px (5.556vw × 8.333vh).
- The outline is an ellipse threshold on that grid: a cell is open when (|x|/Rx)^p + (|y|/Ry)^p <= 1,
measured from the frame: bottom rows inset 5,3,2,1,0 cells → each corner cut by 4 steps.
- Resting mask (ours): Rx = 8 cells (16 of 18 columns → 88.9% width), Ry = 6 rows (100% height), p = 2.
- Intro (ours, from the brief): opens from a stepped diamond 20vw wide (Rx 1.8 cells, p = 1) to rest
in 9 quantised steps over 1.1 s (steps(9)); p ramps 1 → 2 so the diamond becomes the octagon.
- Scroll: over the first 100vh the mask closes back 3 whole steps (Rx 8 → 5) and the photo
scales 1.12 → 1.0 (scrub, ease none).

Values:
- Tile-row marquee: measured drift 69.5 px/s leftwards. The reference's tile row moved
tx -796 → -1422 px across 9.0 s; the same ~70 px per ~1 s kept going with the page at rest,
so the apparent "0.23 px per scroll px" is the time drift itself. We reproduce the drift only.
- Band marquee: auto-scroll with no scroll link. Its speed can't be recovered from one sample,
so it uses the same 69.5 px/s (ours).
- Rows enter: opacity 0 → 1 and transform → none as each row reaches the viewport
(from-offset 40 px, 0.9 s, 'og', ours).
- Header turns to the band colour at 97% opacity once the page scrolls (see main.js).
- Filter: leaving rows fade out in 0.3 s, then the list reflows with Flip (0.6 s, 'og'). */
