Fizzbloom Sparkling Drinks Landing Page AI website prompt
A vibrant beverage template featuring animated 3D cans, playful fruit graphics, interactive flavour selection, and bold typography. Perfect for soda brands, beverage launches, and subscription boxes.
Now put it in WordPress
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.

Frequently asked questions
What does the Fizzbloom Sparkling Drinks Landing Page prompt build?
A vibrant beverage template featuring animated 3D cans, playful fruit graphics, interactive flavour selection, and bold typography. Perfect for soda brands, beverage launches, and subscription boxes.
Which AI tools does the Fizzbloom Sparkling Drinks Landing Page 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 Fizzbloom Sparkling Drinks Landing Page 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.

# MASTER PROMPT — Fizzbloom — Sparkling Drinks Landing Page · 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 `fizzbloom` and write out every file in the appendix below **exactly as written** — do not reformat, rename, shorten, reorder or "improve" anything.
2. **Download the 24 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 match the ASSET MANIFEST below:
```bash
mkdir -p assets

```
Then check every file arrived and none is a zero-byte or HTML error page:
```bash
ls assets | wc -l # expect 27 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:
```
fizzbloom/
index.html
css/style.css
js/can.js
js/fizz.js
js/main.js
js/vendor/CustomEase.min.js
js/vendor/ScrollTrigger.min.js
js/vendor/gsap.min.js
js/vendor/lenis.min.js
js/vendor/three.min.js
assets/
bricolage-grotesque-latin.woff2
fragment-mono-latin.woff2
onest-latin.woff2
chip-bucket.jpg
… 23 more images
```
```bash
zip -r fizzbloom.zip fizzbloom -x '*.DS_Store'
```
Then hand over `fizzbloom.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 fizzbloom && python3 -m http.server 8000 # then open http://localhost:8000
```
Check the page renders, the images load from `assets/` with the network throttled or offline, and scrolling drives the animations.
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
Fizzbloom makes low-sugar sparkling botanical sodas in four loud flavours, sold by the 12-can crate straight to your door.
**10 code files plus an `assets/` folder holding 24 images and 3 fonts, delivered as `fizzbloom.zip`.**
| File | What it is |
|---|---|
| `index.html` | a page, 17 KB |
| `css/style.css` | the stylesheet, 25 KB |
| `js/can.js` | the script, 22 KB |
| `js/fizz.js` | the script, 4 KB |
| `js/main.js` | the script, 33 KB |
| `js/vendor/CustomEase.min.js` | the script, 6 KB |
| `js/vendor/ScrollTrigger.min.js` | the script, 43 KB |
| `js/vendor/gsap.min.js` | the script, 70 KB |
| `js/vendor/lenis.min.js` | the script, 16 KB |
| `js/vendor/three.min.js` | the script, 636 KB |
| `assets/` | 24 images and 3 fonts, downloaded at build time |
**Sections (5):** `#top` · `#inside` · `#lineup` · `#moments` · `#crates`.
---
## ▶ WHAT CHANGED IN V2
- **Natural captions.** Small labels and metadata use sentence case; the large display headings retain the original uppercase treatment.
- **Clear hero heading.** On desktop and tablet, the fruit fan is positioned from the measured heading bounds, with space for navigation. The mobile fruit arrangement remains unchanged.
- **Complete local delivery.** All 24 images and 3 fonts are downloaded into the delivered folder; the five vendor scripts are included in the source appendix.
- **Explicit implementation.** The appendix contains the static implementation. The separate Elementor prompt includes its own builder lifecycle and spacing corrections.
---
## ▶ WHERE THE MEDIA COMES FROM
All 27 files (24 images and 3 fonts) live in `assets/` inside the folder, and every reference in the markup, the CSS and the script is a relative `assets/…` path. Once the folder is assembled it owns its own media: no CDN, no media library, no external image host. Open it on a laptop with the wifi off and it still renders.
They are fetched **once, at build time**, from the WordPress media library on `demo.uichemy.com` — the same `fizzbloom__` files the WordPress build of this page uses. That is only how they travel into the folder; nothing in the delivered code points back at that host. Replacing an image means dropping a new file into `assets/` under the same name.
The manifest below lists every source URL against the filename it is saved as, so the download step is reproducible and checkable.
---
## ▶ HOW THE MOTION IS PUT TOGETHER
Motion combines GSAP and ScrollTrigger, Lenis smooth scrolling, procedural Three.js cans, and a decorative canvas bubble layer.
- Reveals generally run both ways, so scrolling back up replays them in reverse rather than leaving them finished.
- Pinned sections own their scroll distance in the markup, so the document height is authored rather than grown by script.
- `prefers-reduced-motion` is honoured: every animated block checks it and falls back to the finished state, so the page stays readable with motion off.
- The numbers are inline — durations, eases, stagger, parallax speeds. There is no config layer and no control panel; it is plain GSAP.
---
## ▶ DESIGN TOKENS
Everything is driven from custom properties at the top of the stylesheet:
`--sky` `--gum` `--grape` `--sun` `--white` `--black` `--field` `--ink` `--pat-band` `--h-ink` `--h-pill` `--h-pill-ink` `--f-title` `--f-ui` `--f-mono` `--g` `--head-d` `--head-top`
---
## ▶ WHAT THIS PROMPT DELIBERATELY DOES NOT CONTAIN
- No WordPress, no page builder, and none of the wrapper classes or compatibility CSS a builder needs. The WordPress build is a separate prompt.
- No framework, no TypeScript, no bundler, no `package.json`.
- No backend. Any form here validates and replies in place; it posts nowhere.
- No CMS. The content lives in the files.
- No external image host. The images ship inside the zip; nothing in the code calls out to a media library at runtime.

## ASSET MANIFEST — download these into `assets/`
Source is the media library on `demo.uichemy.com`. Save each one under the name in the second column; the code already refers to it by that name.
