Live demo → https://bswxyz.github.io/formwork-chroma/ · How it was built

An iridescent liquid-metal blob raymarched live in a fragment shader — no models, no textures, just math.

A free, MIT-licensed website template. Good for: creative studios, motion designers, anyone who wants a jaw-drop hero. The demo brand ("CHROMA") is fictional — every word and colour is meant to be replaced with yours.

The signature technique

• Signed-distance-field raymarching with smooth-min metaball fusion
• Procedural iridescent environment + Fresnel rim — chrome without an HDRI
• One metaball follows the cursor, so visitors stir the metal

Use this as your own site

This repo is a template — everything is plain HTML/CSS/JS with relative paths, so it works under any repo name with zero configuration.

1. Click Use this template → Create a new repository (top of this page). Name it whatever you like — my-site, portfolio, anything.
2. In your new repo: Settings → Pages → Build and deployment → Deploy from a branch, then pick main / / (root) and save. (CLI: see below.)
3. Wait ~1 minute. Your site is live at https://YOUR-USERNAME.github.io/YOUR-REPO-NAME/.

Prefer the command line?

gh repo create my-site --template bswxyz/formwork-chroma --public --clone
cd my-site
gh api --method POST /repos/YOUR-USERNAME/my-site/pages \
  -f 'source[branch]=main' -f 'source[path]=/'

No build step, no dependencies to install — edit the files, push, done. The only external requests are Google Fonts and (where used) pinned CDN copies of GSAP/three.js.

Customize it

• Blob layout: edit the sphere centres/radii in map() in main.js; smin k-values control melt
• Iridescence: the env() function's cosine palette sets the rainbow banding
• Type: Syne + Space Grotesk via :root / Google Fonts — swap freely

The /guide/ page documents the signature technique in depth (with code) — keep it, rewrite it, or delete the folder entirely.

Files

index.html        the page
styles.css        all styling (design tokens in :root at the top)
main.js           the signature effect + motion
guide/index.html  how-it-works write-up (optional — yours to keep or delete)

Built-in quality

• Works with JS disabled or a CDN failure (content is never permanently hidden)
• Respects prefers-reduced-motion; keyboard focus styles throughout
• Canvas/WebGL feature-detected with graceful fallbacks; devicePixelRatio capped for performance
• Responsive at phone / tablet / desktop widths
