# Checkmark filter chips

> A small dot spins and turns into a tick when you switch an option on. Several chips can be active.

## Where to use it

Use these when people can combine options, like the amenities on a holiday rental site: wifi, pool, parking, pets allowed. The tick makes the difference between on and off obvious, which matters when four or five filters are active at once. Handy if you are looking for multi-select chips or checkbox chips in HTML and CSS.

Because they toggle, update the list or the result count right away, so people see each tap doing something. Avoid them for choices where only one answer makes sense, like sort order. There a segmented control is clearer.

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 “Checkmark filter chips” block (Filters) from AIMRAN Library to my project.

## What it is
A small dot spins and turns into a tick when you switch an option on. Several chips can be active.

## 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.
