A garden design studio's four services told at reading pace: the service names stay pinned on the left, the one you're reading lights up with a thin rail filling as you go, and the right column scrolls through a plan drawing, a planting palette, material swatches and a care calendar; click a name to jump there.
One scroll handler, two outputs: the same rect maths gives both which title is active and how far the rail is filled, so the left column reads as a live table of contents rather than a set of anchors.
From prompt to a block in your page.
The preview is the shipped block inside a neutral demo page. Scroll, hover, drag: everything is live.
Token sets re-tint the block live. The prompt carries the one you chose.
A paste-in snippet, or a component for Next.js, React, Vue, Astro, WordPress, Shopify or Webflow.
It quotes the block's markup, styles and script verbatim with the tokens and the rules that keep it self-contained.
Add the head lines it names, paste the block, replace the placeholder copy. Tokens live on :root.
