# Fragrance pyramid filter

> A perfume's notes in its top, heart and base pyramid: each glass tier lights up and evaporates as you pick notes.

## Where to use it

Perfumers describe a fragrance as a pyramid of top, heart and base notes that fade at different speeds, and this filter uses that structure directly. Each tier is a clipped glass slice beside its chips; ticking a note lights its slice and releases particles that rise fast at the top and slowly at the base. Checkboxes and CSS do all the work.

The first colour tints the top and heart tiers and the second the base, from amber to plum. Replace the notes and the times with your own catalogue, and use it in perfume shops, candle brands or tea blends.

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Fragrance pyramid filter” block (Filters) from AIMRAN Library to my project.

## What it is
A perfume's notes in its top, heart and base pyramid: each glass tier lights up and evaporates as you pick notes.

## Chosen settings
- Main color: #c08a3e
- Secondary color: #8e4b8a
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Notas del perfume"

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
