## Where to use it

This checkbox celebrates. It suits the moment someone finishes something they care about: ticking off a daily habit in a habit tracker, completing the last step of an onboarding checklist or marking a lesson as done in a language course. Eight dots in your two colors burst out of the box while the tick draws itself.

Save it for achievements. In a long form with ten checkboxes, the confetti gets old by the third one. Particles escape the box, so give it a bit of room, especially when checkboxes are stacked close together.

````text
I want to add the “Confetti burst checkbox” block (Checkboxes) from AIMRAN Library to my project.

## What it is
Checking the box fires eight little particles outwards, a tiny celebration for getting something done.

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

## 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.
