# Filter chips with counters

## Where to use it

Counts help people decide where to click. On a community forum you might show how many threads sit under General, Help, Showcase and Jobs; in a support inbox, how many tickets are open, pending or solved. The little hop draws the eye when a number updates, without shouting. Good for anyone searching for filter tabs with a badge count.

The numbers need to be real and current, or the whole idea backfires. If a category is empty, consider greying out the chip instead of hiding it. And keep counts under three digits where you can; “999+” is perfectly fine.

````text
I want to add the “Filter chips with counters” block (Filters) from AIMRAN Library to my project.

## What it is
Each chip carries a small count, and the number does a quick hop whenever it changes.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)

## 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.
